@John and I explained that is unfortunately not possible, but wanted to suggest that the magic option in a world that already has dragons is still pretty awesome. Quenching is the process in which steel is cooled from extremely high temperatures to not so high ones. A high Youngs modulus, therefore, means a generally strong material as it will not plastically deform under increasing loading conditions. resistance. Consequently, they need many unique adaptations just to avoid bleeding to death or becoming permanently disabled in the course of their frequent scuffles. This article presented a brief summary of the properties, strength, and applications of phosphor bronze. Specifications Met: ASTM B139. Modulus of elasticity, or Young's modulus, describes the ability of a material to elastically deform- that is, how stiff a material is. rev 2020.12.18.38240, The best answers are voted up and rise to the top, Worldbuilding Stack Exchange works best with JavaScript enabled, Start here for a quick overview of the site, Detailed answers to any questions you might have, Discuss the workings and policies of this site, Learn more about Stack Overflow the company, Learn more about hiring developers or posting ads with us. Phosphor bronzes meets many designer specifications and is a proven engineering material. Aren't there any additives that would make it happen in quenching temperatures? You don't want harder steel, it breaks, you don't want softer steel, it bends, you want more control of the temperature of the steel at every stage so you can get the exact properties you want. While most blades, to this day, are made using water or oil as the quench medium in the traditional quenching and tempering process that James mentions, producing a tempered martensite microstructure, this is actually not the ideal microstructure for a given hardness. 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. improve machining characteristics and atmospheric corrosion Visit us Today! Tungsten vs Tungsten Carbide - What's the Difference? While you do this you keep the cutting edge cool either by keeping it in liquid or wet clay or something, this keeps the edge hard. 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. Copyright© 2020 Thomas Publishing Company. A thin coating of mercury or arsenic on a blade can dramatically increase the killing effectiveness of the steel. Modern production dunks the part in a molten salt (nitrite/nitrate) bath that cools the part to an isothermal transformation temperature, then holds it there to effect the transformation before pulling it out and letting it air-cool post-austemper, or uses special alloys that can form bainite during a continuous cooling process. It puzzles me why people refer to their guitars as "axes" or "weapons." Bats blood? Slow, and intolerant of cold weather. magnetised steel doesnt remain magnetic forever. Would France and other EU countries have been able to block freight traffic from the UK if the UK was still in the EU? This alternative has the advantage that the blade could be handled, cleaned and cared for as long as it never came in touch with blood. The addition of lead will make phosphor bronzes stronger and more machinable, but unleaded phosphor bronzes are also strong and resistant by themselves. The direction of rotation of the vortex is reversed every half-cycle of the oscillation. When stored in the structure of cold steel, the microscopic life lays dormant until revived by hot human blood. (All compositions mentioned in this article refer to percent by weight.) itss owne wille. you can demagnetise it. This of course assumes that the blood swords are forged to a high quality per James' answer. Most alloys form an attractive patina in the presence of oxygen and are therefore also useful for decorative applications. The phosphor-bronze stripes bend, periodically, backwards and forwards in a reproducible way. Worldbuilding Stack Exchange is a question and answer site for writers/artists using science, geography and culture to construct imaginary worlds and settings. 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. 0.01–0.35% phosphorus. Biblical significance of the gifts given to Jesus. 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. A basic introduction to heat treatment of steel. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Dragons' blood is an absurdly good insulator. It may be helpful to review our article on the types of bronzes, so as to understand the commonalities between copper alloys and their popular applications. reddit.com/r/metallurgy/comments/2fyqf6/monocrystalline_steel, https://www.totalmateria.com/page.aspx?ID=CheckArticle&site=kts&NM=211, bladeforums.com/threads/quench-speed.1155941. 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. I hope this makes sense and is helpful. The nation that forges their swords in the blood of dragons and then quenches the sword in the blood of their enemies? For example, if etching and inlay is part of your application, phosphor bronze may be a good balance between strength and workability, but this is dependent upon the specific alloy type and strengthening procedures. So in order to make dragons blood superior for quenching to water, we need to find its one flaw. Are dragons common enough that you can maintain a workable supply of the stuff? Nowhere said faster than water. Quenching a blade in Dragons' blood is not like a normal quenching - it's more like aging a whiskey. Now, normally this would not be quite what you want for quenching, but Dragons' blood is also magical. It can be that dragon's blood happens to conduct heat really well, making a harder blade. 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. Poisonous, and likes to bite the hand that wields it. 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. 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. You need no special chemical properties or materials, just the right ratio of water to not water. The entire book was found in a rather scorched-around-the-edges condition outside of The Great Smoking Cave. See All About Aluminum Bronze - Strength, Properties and Uses. The problem is, it is a very thin layer, and depending on the type of steel may actually flake off. Which “Highlander” movie features a scene where a main character is waiting to be executed? 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. annye othere, beinge unbrakeable, undullable, magicallee sentient annd possess'ed of It will make it brittle. Product details They are most often used for corrosion-resistant applications, as well as in other applications that need a springy-yet-durable material. Dragon's blood? 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. 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. The work of Bain and Davenport at US Steel in the 1920s and 1930s (pat. Once that is done you reheat the blade but only along the spine back to a cherry red, say 800 degrees or so. Maybe they are bronze. @JustinThyme Certainly, so long as it still works as blood. Tougher blades, though, are generally considered better- they snap back better to their original shape and don't become bent as easily. The alloys typically contain up to 10% tin and up to 0.35% phosphorus. when you quench metal in this blood you will benefit from its properties. In strip form, they are widely used for, among other things, electrical and electronic connectors. Phosphor bronze is an alloy of copper with 0.5–11% of tin and 0.01–0.35% phosphorus. ferrite. Damascan steel managed to get very strong and still elastic through nanowires and carbon Nanotubes that were enclosed in the metal. 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. Annealing Bronze. Peace out guys, I'll pass. Alloy 510 phosphor bronze strip, ASTM B 103, offers excellent corrosion resistance and good strength and electrical conductivity. 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. Materials for Engineers and Technicians, 4th-2006_(Raymond A. Higgins).pdf pages: 415 Website Last Modified December 23, 2020. If it is too strong, it would make it really difficult to sharpen the blade. while the steel is easily manipulable the magnetism would align the grain to a more perfect form right? If you had Bronze Age tech, phosphor bronze would be excellent sword making stuff. awesome answer. Dragons blood you see, it contains metals that get heated when it breaths fire and then they are cooled in a controlled way by the blood. Can flex better with losing strength. That being said if you are working in a fantasy realm...which I would assume you are since...you know...dragons, you can use the ol' it's magic and create something that works for story telling. This banner text can have markup.. web; books; video; audio; software; images; Toggle navigation Product Name Phosphor Bronze Alloy Chemical Name Metal Alloy Synonyms Copper Tin Phosphorus Alloys, Alloy Nos. Electrical conductivity (relative to pure copper). We have a great online selection at the lowest prices with Fast & Free shipping on many items! Or a simple hang blade here and turn the hand crank until the blade is in the blood type of machine. Aided by the intrinsic magic of the blood purifying the lattice and eliminating dislocations, the end result is a nigh-indestructible monocrystalline blade which requires no further tempering. Better is more control of the process. Well, now - that's a bit of a poser. Alternatively, the poison could be biochemical. Phosphor bronze is a member of the family of copper alloys. The most It is a useful measure for fabricators when machining, as well as in applications where the material must keep its form without jeopardizing the structure’s integrity. Imagine facing an army who's reputation is: You mean we are fighting the XYZ's? DO NOT use CA to hold anything in position for soldering. What qualifications are used to consider a sword "better" if it is treated with blood? Additionally, increased hardness usually comes with increased brittleness, increasing the chances of a blade shattering. Gibbs stocks Grade A phosphor bronze in spring temper (8#'s hard) in the B 92-98 Rockwell range. This material is usually used to make springs and bolts, as well as similar items. 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. embrittlement... Get the best deals for phosphor bronze washers knife at eBay.com. Phosphor bronze is an alloy of copper with 0.5–11% of tin and Once done, the part would be removed from the bath, washed, and for a blade taken straight to the grinding wheel for sharpening, as austempered parts need no further heat treatment. The addition of tin will increase this resistance along with its strength, and the addition of lead will make a phosphor bronze that is colloquially known as the “Machinist’s friend” (alloy COLPHOS 90/C54400), as it is nearly indistinguishable from free-cutting brass alloys. 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. The diversification of bronze can make material selection difficult, however, so this article will help alleviate some confusion by exploring one kind of bronze, the phosphor bronzes. 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). @EliasRowanAlbatross Poison is more or less pointless on a sword, especially arsenic, you need to take in a lot of arsenic to bother someone. +1, What I would have gone for. Iron content? You could also just use distilled dragon blood. It generally doesn't matter what type of fluid you quench your blade in. Below, in Figure 1, is a qualitative chart depicting the composition of phosphor bronze: From examining Figure 1, it may be difficult to understand why phosphor bronze is named as such when it is mainly an alloy of copper and tin. site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. 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. First, being elemental carbon, it can be used in the production of weapon-grade steel. For additional information on our phosphor bronze rods, or any of our product lines, get in touch with our sales on 0121 525 5500. It only takes a minute to sign up. A: This will be easier to do if the bronze piece is annealed first. Then you would temper the spine. According to a few pages I just read nothing is faster at dispersing thermal energy from other materials than water. If you were to equate it to a D&D campaign, you would be close enough for proverbial government work. and stiffness of the alloy. ye grate wurk! The blade then cools incredibly slowly. The tin increases the corrosion resistance and strength of the alloy. Phosphor bronze has a decently high elastic modulus (almost half that of most steels), which suggests it is not as strong as other alloys but can hold its own under moderate conditions. So, while most phosphor bronze alloys are somewhat difficult to mill, this issue can be addressed with the right alloy selection. Most forges and quenches can not be targeted to the exact temperature, quenching fluid in particular boils off before it can be heated to the best temperatures. Fiducial marks: Do they need to be a pad or is it okay if I use the top silk layer? 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. NOT GOOD! You don't need to rough them up. GHS A260 Phosphor Bronze Mandolin Strings - .011-.038 .011-.038 Medium Light Gauge Mandolin Strings, Phosphor Bronze, Loop-end, Bobby Osborne Signature $6.19 $ 6 . Being magnetically aligned is probably a net bad,getting stuck to you opponent sword or armor might get you killed. Where else can you have a conversation about the practical uses of distilled dragon blood? (This also explains why Dragons sleep on hoards of gold and treasures made from other metals - the magic in their blood interacts with the metal, giving them the same basking feeling that a lizard gets in the hot sun). But then with using dragon's blood to quench the blade at just the right temperature and speed, you can make your blade stronger but lighter, and thereby use fewer metallic resources, and thereby bring the finished blade into the wieldable and affordable range. But there are solutions. 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. What is this stamped metal piece that fell out of a new hydraulic shifter? It resists wear, stress and marine corrosion, and can be polished to a rich, golden shine. It's commonly called phosphor bronze. Elixir Strings Nanoweb Phosphor Bronze Acoustic Guitar Strings -.012-.053 Light .012-.053 Nanoweb Light Gauge Acoustic Guitar Strings, Phosphor Bronze C54400 Phosphor Bronze. By using our site, you acknowledge that you have read and understand our Cookie Policy, Privacy Policy, and our Terms of Service. Swords, knives, spears, axes etc. An excellent material for use in the manufacture of bearings, C54400 B-2 Phosphor Bronze is also extremely machinable. This causes phosphor bronze to be both useful for shaping operations and more difficult to machine, but more on this in a bit. -, :P and then there are people like this: "I've been using canola oil for quenching my 5160" -. Always use flux, for any soldering. Molten salt is also extremely dangerous. If you then use folded steel and quench between foldings you create many layers of this coating inside the blade, making them have superior properties in strength, resilience, maintenancr and resistance to damage/shattering.
