You might want to read my answer. Dance of Venus (and variations) in TikZ/PGF. At, @VilleNiemi -- that could work for temperature regulation as well, but would have some disadvantages in terms of getting parts in and out of the bath. A professor I know is becoming head of department, do I send congratulations or condolences? First, being elemental carbon, it can be used in the production of weapon-grade steel. drawability... Phosphorus is also used as an additive in steels to It is also not as strong as other, more harden-able alloys such as steel, which can be good or bad depending upon the application. Well cooling metal too slowly results in it being too soft but cooling it too fast results in it being hard but brittle. You could make dragon blood exceptionally high - perhaps they need a lot of circulating ATP to produce fire. The general thing to know is that the faster the steel cools down from critical (the point where it is so hot it is no longer magnetic) the harder and more brittle it becomes. If you had Bronze Age tech, phosphor bronze would be excellent sword making stuff. Table 1, below, shows some mechanical properties relevant to phosphor bronze’s uses and strengths. It would be safer for it's wielder to carry than the elementally poisoned blade described above. @JustinThyme Certainly, so long as it still works as blood. Semi-plausible reason why only NERF weaponry will kill invading aliens. Types of Tungsten Alloys - Properties and Uses, All About Bearing Bronze - Strength, Properties, and Uses, 9 Types Of Email Marketing You Should Be Sending, How To Grow Your Packaging Company Online, 8 Reasons It's Great To Work In Manufacturing. Description SPBY04PGY2: Meadowlark 2 FRN - Gray byrd Knife Designed by Spyderco Already one of the best values in the popular byrd line, the Meadowlark Lightweight has been completely re-engineered to yield the improved Meadowlark2. NOT GOOD! Graphite is a blacksmith's friend for three reasons. The problem is, it is a very thin layer, and depending on the type of steel may actually flake off. This banner text can have markup.. web; books; video; audio; software; images; Toggle navigation lubrication is generally not an issue with sharpening, oils and such are used to protect the stone so it can be reused, not to make for a sharper blade. Just because it doesn't work in real life doesn't mean it can't be awesome in a story. Rhinoceros blood? that is water cools steel so quickly that it doesn't cool evenly which is absolutely necessary to create perfect steel. itss owne wille. Any ideas? What happens during the quenching is that these materials coat the blade, providing a superior resiliance to shattering, dentation and needing less effort to remain sharp. Phosphor bronze has been used for many years in electrical components, but it is still finding new uses thanks to technological advances and the demand for more specialized materials. with a stoked fire, and the parts would be held in the quench medium for a significant length of time (quite a few hours), effecting an isothermal austemper and producing tougher, stronger blades for a given hardness at a minor tradeoff in absolute hardness achievable. Perhaps the dragon's blood is high in elements which are inherently poisonous to humans. Counterintuitively, a higher Youngs modulus suggests a more elastic material, but this is not a measure of “stretchiness”; it is a measure of internal material strength and how likely the material is to return to its original shape in the presence of an increasing force. Use Mercury as quenching liquid for swords? Visit us Today! This also allows it to be used in a liquid oven or normalizing medium, which means the steel can be heated perfectly evenly and kept there as long as necessary. Something I heard in a Materials Science class, supposedly the Conquistadors' blades were quenched by running a captive Inca through with a blade to quench the blade. According to a few pages I just read nothing is faster at dispersing thermal energy from other materials than water. The phosphorus … In addition to bearings, it is often used for shafts, gears, and valve parts. D’Addario EXP16 Coated Phosphor Bronze Acoustic Guitar Strings, Light, 12-53 – Offers a Warm, Bright and Well-Balanced Acoustic Tone and 4x Longer Life - With NY Steel for Strength and Pitch Stability. Phosphor bronze is a member of the family of copper alloys. The phosphorus increases the wear resistance and stiffness of the alloy. 19 improve machining characteristics and atmospheric corrosion magnetised steel doesnt remain magnetic forever. .410 gauge shotgun chamber brush outers phosphor bronze 415753 omark industries 415753 / 1029-0 - .410 ga: $1.00:$2.00 12-19 10:10: 17118185: weaver ironsighter bases model irl-acc-la new sealed in package long action all models with accutrigger matt / 35-8: $6.00:$9.00 12-19 10:20: It's commonly called phosphor bronze. Quenching a blade in Dragons' blood is not like a normal quenching - it's more like aging a whiskey. I like the idea (especially the "aged like whiskey" part), but I don't think mono-crystals behave like you think they do: @GarrettMotzner A flawed monocrystal with dislocations certainly wouldn't - excessive stress could cause propagation of dislocations and generate a grain boundary - but a flawless monocrystal would lack those 'nucleation points' for the weakness to occur at. -, :P and then there are people like this: "I've been using canola oil for quenching my 5160" -. Materials for Engineers and Technicians, 4th-2006_(Raymond A. Higgins).pdf pages: 415 Once that is done you reheat the blade but only along the spine back to a cherry red, say 800 degrees or so. Can you improve on your regular sword by sticking it into a dragon? Wikipedia shows a phosphor bronze ship propeller - for tool making applications this would be great, and a dip in high phosphorus dragon blood would be a way to get a layer of phosphor bronze on the outside of your bronze weapon. It is really easy to overheat or underheat the steel. Whatever would be viable improvement, and is scientifically possible. Q: I need to bend a thick piece of bronze, but it is too stiff. Tungsten vs Tungsten Carbide - What's the Difference? They are most often used for corrosion-resistant applications, as well as in other applications that need a springy-yet-durable material. Sadly, with science...it doesn't. Horse blood? Online description: Phosphor Bronze delivers the widest range of sound of any Black Panther snare. you can demagnetise it. California Do Not Track Notice. Tougher blades, though, are generally considered better- they snap back better to their original shape and don't become bent as easily. Product details CopyrightÂ© 2020 Thomas Publishing Company. So, while most phosphor bronze alloys are somewhat difficult to mill, this issue can be addressed with the right alloy selection. awesome answer. I hope this makes sense and is helpful. See @John "make the cooling faster than that of oil or salt bathing, but not as fast as water." Because of their increased tensile strength, phosphor bronze and silicon bronze were favoured by some, but hard-drawn copper held the field until the brittleness of bronze was overcome. All About Aluminum Bronze - Strength, Properties and Uses. Dragons are fierce creatures the size of small commercial jets. Leaps into your hand, but really touchy about what it eats/hits - insists on second-cutting hay, gets colic-y at the drop of an anvil, and is prone to develop hoof/grip problems. C50500, 50700, C51000, C51900, C52100 Chemical Family Copper Alloy Formula Not applicable - mixture Product Use Metallurgical Products Company Address Fisk Alloy PO Box 26 10 Thomas Road Hawthorne, NJ 07507, USA MSDS Issue Date 12/1/2009 The OP does specify they want a non-magical effect. Quenching in Dragon's Blood thus deposits a microscopic coating that happens to bond to steel really well (due to little understood adaptations for rapid bone regeneration that apparently rely on high concentrations of several organometallic compounds dissolved in their blood) and which far exceeds the performance of any synthetic materials we can hope to make. Making good steel is about precision, you are trying to hit a bullseye of qualities. $11.99$ 11. If it can cool metal weapons quickly enough and achieve the "glass metal" mentioned above, it will be tougher which will result in a better blade. Brine cools steel faster than normal water, faster cooling is not good for a sword, it makes steel brittle. The final step in heat treating is tempering. True about the composition changing. 30. If your company can help provide supplies, capabilities, or materials for products such as N-95 Masks and Tyvek Suits â Please let us know. Now, normally this would not be quite what you want for quenching, but Dragons' blood is also magical. Why would that be? Stay up to date on industry news and trends, product announcements and the latest innovations. Enlist Your Company ico-arrow-default-right. You need no special chemical properties or materials, just the right ratio of water to not water. The blade then cools incredibly slowly. As with most physical laws, in the presence of a sufficiently dense magical field the square-cube law decides that it's time to go out for a smoke and perhaps a pint down at the pub, and leaves the world (and the dragons) to their own devices. Basically molten salt, without all the problems molten salt has. Phosphor bronze is used for springs, bolts, and various other items used in situations where resistance to fatigue, wear, and chemical corrosion are required (e.g., a ship's propellers in a marine environment). https://www.totalmateria.com/page.aspx?ID=CheckArticle&site=kts&NM=211. Like hardness, machinability is a comparative measure of a material’s ability to be machined and is always in reference to some standard machining material (for the bronzes, this material is UNS C36000 – free cutting brass). You can't incorporate anything into the steel by quenching it it, if you added it while the steel was still molten you might be able to incorporate it, but steel is not liquid enough to diffuse into during a quench. It puzzles me why people refer to their guitars as "axes" or "weapons." It even makes sense that dragons would have such blood since they need blood that will not boil no matter how hot they are. When quenching hot steel in dragon's blood, the liquid effectively becomes a kiln that cools weapon steel evenly and, by coincidence or godly design, at the ideal rate that ensures maximum hardness. Fiducial marks: Do they need to be a pad or is it okay if I use the top silk layer? Elves, goblins, dragons, magic. It is composed of copper that is alloyed with 0.5–11% of tin and 0.01–0.35% phosphorus, and may contain other elements to confer specific properties. They are also resistant to fatigue, meaning they retain their strength over many cycles of loading. Always use flux, for any soldering. It is the most dramatic moment of the forging process and is generally shown in entertainment as the last step...it's not. Modulus of elasticity, or Young's modulus, describes the ability of a material to elastically deform- that is, how stiff a material is. When I am forging bronze I judge the time in the fire by turns of the blower crank rather than by color of the metal. In this process, the quench tank would be almost like a cauldron, kept hot (but not too hot!) This means it can control the temperature the steel is cooled to exactly. Grades A, C, and E – C51000, 52100, 50700 are commonly used nonferrous spring alloys. The addition of lead will make phosphor bronzes stronger and more machinable, but unleaded phosphor bronzes are also strong and resistant by themselves. No, diffusion is pretty straightforward in solids. Bats blood? Phosphor bronze is a copper alloy. Phosphor bronze has an impressive yield strength, matching some aluminum alloys and surpassing even other bronzes, and this is thanks to its high percentage of tin and phosphorus. Swords, knives, spears, axes etc. But, it is a "cleaner" so, without getting into the whole thing about what a metal cleaner does, you have to understand that break free is used to clean gun parts. The alloys typically contain up to 10% tin and up to 0.35% phosphorus. Gibbs stocks gauge ranges from 0.006" - 0.031" (9 ksi) while also improving the bake hardening response and deep You don't need to rough them up. Would France and other EU countries have been able to block freight traffic from the UK if the UK was still in the EU? Dragon's blood? The grain type shown in the recovery part of that graphic reminded me of a chart i saw related to magnetism and this gives me an idea, what if the blood is magnetic for whatever reason? Aren't there any additives that would make it happen in quenching temperatures? A thin coating of mercury or arsenic on a blade can dramatically increase the killing effectiveness of the steel. Although I was thinking along the lines of the blood actually boiling. One of those adaptations is an advanced clotting factor in their blood. Off topic. quenching a sword in a phosphorus will have zero effect on the phosphorus content, its not hot enough to be incorporated, and any thin crust will be ground off during sharpening. By examining the physical, chemical, and mechanical properties of phosphor bronze, this article aims to help interested designers determine if this copper alloy will be applicable to their projects. You heat the blade to white-hot, plunge it into the blood, seal it up, and leave it for a month or so. The alloy is also used in some dental bridges. Bronze is improved in hardness and strength by the addition of a small amount of phosphorus; phosphor bronze may contain 1 or 2 percent phosphorus in the ingot and a mere trace after casting, but its strength is nonetheless enhanced for such applications as pump plungers, valves, and Alloy 510 phosphor bronze strip, ASTM B 103, offers excellent corrosion resistance and good strength and electrical conductivity. They are exceptionally elastic in nature, resistant to fatigue and corrosion, and are readily formable, castable, and solderable. ferrite. As mentioned above, 80/20 strings produce a crisp, bright, and projecting tone that many vintage guitar enthusiasts love. To do this you first harden the blade by quenching it as mentioned. Interesting, but the problem is the sharpening. Iron content? Materials with lower hardness values are generally softer, meaning they are more easily scratched, dented, and locally deformed on their surface, while higher numbers suggest a material that is difficult to scratch (think borosilicate glass, ceramic, etc.). Company. The CF Martin D-45 Excalibur is the latest design collaboration with renowned inlay artist Harvey Leach. Hardness: Hardness is a measure of how much force it takes to deform the steel. Still I am guessing you'd want some specialized tool that lets, say two people, to carry the blade, put it in and take it out while maintaining a reasonable distance. 0.01–0.35% phosphorus. it will just have a well aligned grain that absorbs shock better than other swords and would thus not break as easily. Quenching a sword in blood imbues the properties of the blood (and by extension the animal from which the blood is drawn) into the sword. Making statements based on opinion; back them up with references or personal experience. @Bewilderer Any improvement without a noticeable detriment. familiar example in this category is the classic phenomenon of temper For information on other products, consult our additional guides or visit the Thomas Supplier Discovery Platform to locate potential sources of supply or view details on specific products.150. It resists wear, stress and marine corrosion, and can be polished to a rich, golden shine. Terms and Conditions, But with proper timing and sizing you can make it so that the blood has just stopped boiling before you put the parts in or take them out. Table 1 shows hardness values from the Rockwell B scale, which is often used to describe the hardness of copper alloys and other metals. Detrimental effects of phosphorus in steel include various forms of It won't matter if can recondense the steam back or replenish the blood for the duration and the vessel is of sufficient size. Asking for help, clarification, or responding to other answers. What is the relation between a priori and tautologies? If it sounds attractive to your application, be sure to contact your supplier, as they will have the newest alloys available. Below is a list of phosphor bronze applications but know that it has many uses outside of this list, and new applications are still being developed. Austempering really seems to be the only realistic option. When you quench the blade in any substance, the outer layer will indeed bond with the quenching fluid (we use a mix of motor oil and antifreeze at my shop). How long does it keep? Can flex better with losing strength. The nation that forges their swords in the blood of dragons and then quenches the sword in the blood of their enemies? Actually pretty bad, since people whose blood is being used to quench the sword are obviously LOSERS! I really love worldbuilding. Gibbs stocks Grade A phosphor bronze in spring temper (8#'s hard) in the B 92-98 Rockwell range. I offer you another reason why these swords are perceived as "better" and that reason is psychology. It's "better than water through a better ratio and cooling process due to chemical properties". Lizard blood? ye grate wurk! One exception is that, in this world, it is popular to quench newly forged swords in dragon's blood instead of oil (or gods forbid, water). What Is Phosphor Bronze? Visit us Today! It will make it brittle. This is known as austempering, and is commonly used for high-strength steel parts such as rifle bolts (all the way back to WWII), mower blades, and seat belt parts in cars. Are we free to alter the chemical composition of dragons' blood to whatever we need it to be? the way I imagined it, you'd want the blade razor sharp before the final dip in dragon's blood, & afterwards you wouldn't be able to sharpen it per se, but the coating would be so thin & abrasion resistant that you would only want to hone or polish it the smallest amount anyway. Mostly because excess amounts will collect dust, dirt and grime in your pivot. If the wielders are brainwashed into thinking their swords are better through questionable demonstration of a blood-sword versus a purposely built brittle sword then their confidence in battle will simply be higher. imagine a slow, magnetized cooling. Material hardness is always relative to some standard hardness machine, and the various hardness scales provide a comparative list of materials within the same general class/material. With that in mind, suppose you had a different alloy, one that under normal forging processes would either be too expensive for your average customer to buy, or too heavy for them to wield. Maybe they are bronze. Tone Compared: Phosphor Bronze vs 80/20 Bronze. Snakes blood? While not a standout alloy in any one of these categories, its ability to be both resistant, strong, and conductive means electrical components made from phosphor bronze will last longer than copper analogs. ico-arrow-default-right. The Old Metallurgical Engineer and Steelmaker says: For a non-ferrous sword, I would go for a titanium alloy, either Ti-13V-11Cr-3Al or a Ti-8Mo-8V-2Fe-3Al, both of which have a yield strength of 1100MPa. Why would people invest in very-long-term commercial space exploration projects? It consists of a mix of copper, tin, and phosphorus, hence its name. Are we assuming that blacksmiths just have vats of dragon blood on-hand? The tin increases the corrosion resistance and strength of the alloy. This material is usually used to make springs and bolts, as well as similar items. Finally, graphite is a superb lubricator, and the use of dragon's blood while grinding a dragon steel blade is known to yield the sharpest possible edge. Or a simple hang blade here and turn the hand crank until the blade is in the blood type of machine. hand forged, tempered and fully functional wherever, whenever you need a little piece of history. Why does 我是长头发 mean "I have long hair" and not "I am long hair"? C54400 Phosphor Bronze. Such materials could be present in dragon's blood especially if parts of the dragon were ground into the blood. Where else can you have a conversation about the practical uses of distilled dragon blood? Therefore, phosphor bronze has been used for a long time as a material in electrical switches, fasteners, connectors, and more, as it can bare both mechanical and electrical loads better than typical copper counterparts. Peace out guys, I'll pass. And while still being viable blood for a living creature? It could be beneficial if it has the right properties. Phosphor Bronze is an alloy of copper, containing 3.5 to 10% tin and a phosphorus content of up to 1%. Phosphor bronzes meets many designer specifications and is a proven engineering material. That hardens the outer layer, where you want it to hold and edge. Privacy Statement and Damascan steel managed to get very strong and still elastic through nanowires and carbon Nanotubes that were enclosed in the metal. The blade must then be sharpened by magic, resulting in this monomolecular blade having an edge only a handful of atoms thick - but despite the magic involved in the forging process, no actual magical properties are imposed on the sword itself. @Xavon_Wrentaile on the plus side of things, even if sharpening wore off a bit on the edge, rust would be a non-issue for most of the blade surface, that's a good point. Biblical significance of the gifts given to Jesus. MathJax reference. Metallurgy really doesn't allow for a scientific benefit to using dragon blood...which is great for your dragons. DO NOT use CA to hold anything in position for soldering. Below, in Figure 1, is a qualitative chart depicting the composition of phosphor bronze: Save more with Subscribe & Save. Why is this gcd implementation from the 80s so complicated? Known for its ability to resist stress cracking and fatigue, 544 bronze also offers good formability and excellent machinability. resistance. It will be a pain anyway. Phosphor bronze can be bought with increased lead levels that will remove its machining difficulty, as it becomes more self-lubricating. @EliasRowanAlbatross Poison is more or less pointless on a sword, especially arsenic, you need to take in a lot of arsenic to bother someone. Nowhere said faster than water. Either way you would grind and polish after hardening. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. The combination of good physical properties, fair electrical conductivity, and moderate cost make phosphor bronze round, square, flat, and special-shaped wire desirable for many s… ...

For those of us who are not up-to-date on their material science, quenching has the end effect of making metal harder. Most phosphor bronze alloys are tarnish and corrosion resistant, making them useful in electrical conduit and other caustic environments. Additionally, cooling some metal quickly enough can result in it being amorphous. Makes for a nice, lightweight blade, very quick and easy handling, but it squeeeeeeaks every time you draw it out of the sheath - puts everyone's teeth on edge, and obviously no good for a ninja. For the most part, this material is used in the marine industry, because it is very anti-corrosive. The people understand germ theory, and atoms (though not sub atomics). Imagine a typical fantasy world. Second, graphite is an excellent refractory material able to provide stable heat insulation across a wide range of temperatures. Are dragons common enough that you can maintain a workable supply of the stuff? but good point about a bronze sword being possible. Animals run on ATP which is a high energy phosphorus compound and so all blood has a lot of phosphorus. It is a common measure of a material’s non-yielding strength, as stress below this point will not bend or stretch the alloy (though, there are always exceptions). This is how the best steels are produced and how to get the most out of your steel allows, precision control of temperature at every stage.
