Phosphor bronzes meets many designer specifications and is a proven engineering material. 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. One of those adaptations is an advanced clotting factor in their blood. Posted in Fire, Metal, Werby’s Q and A on Techniques. Perhaps the dragon's blood is high in elements which are inherently poisonous to humans. Enlist Your Company ico-arrow-default-right. 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. In this process, the quench tank would be almost like a cauldron, kept hot (but not too hot!) Phosphor bronze is an alloy of copper with 0.5–11% of tin and Only about 3 to return it to working temperature while working it. These alloys are notable for their toughness, strength, low coefficient of friction, and fine grain. ye grate wurk! site design / logo © 2020 Stack Exchange Inc; user contributions licensed under cc by-sa. it will just have a well aligned grain that absorbs shock better than other swords and would thus not break as easily. Making statements based on opinion; back them up with references or personal experience. Visit us Today!

By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. Animals run on ATP which is a high energy phosphorus compound and so all blood has a lot of phosphorus. 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). First, being elemental carbon, it can be used in the production of weapon-grade steel. Alloy 510 phosphor bronze strip, ASTM B 103, offers excellent corrosion resistance and good strength and electrical conductivity. 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. Most phosphor bronze alloys are tarnish and corrosion resistant, making them useful in electrical conduit and other caustic environments. You could also just use distilled dragon blood. I really love worldbuilding. Tensile yield strength is a stress value that determines the point after which the material will plastically deform. 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. 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 Biblical significance of the gifts given to Jesus. We may have to talk blade making in chat, I am curious which blades you wouldn't want to differentially treat. Perhaps the dragon's blood contains a voracious infection which thrives in the scalding bloodstreams of dragons. Phosphor bronze can be bought with increased lead levels that will remove its machining difficulty, as it becomes more self-lubricating. Quenching is the process in which steel is cooled from extremely high temperatures to not so high ones. 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. Phosphor bronze is a member of the family of copper alloys. Peace out guys, I'll pass. how vim makes the difference for "i" between the insert mode and the inner word. Off topic. Just because it doesn't work in real life doesn't mean it can't be awesome in a story. ferrite. Can you improve on your regular sword by sticking it into a dragon? It's a little-known fact that dragon's blood has an exceptionally high graphite content, a byproduct of their evolution from the igneous realms of the molten hearts of mountains. 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. Being magnetically aligned is probably a net bad,getting stuck to you opponent sword or armor might get you killed. 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. Most alloys form an attractive patina in the presence of oxygen and are therefore also useful for decorative applications. For example, bringing a cold 1/4" round bronze brazing rod to working temperature in my forge takes about 10-12 blower turns. This is because it only takes a small percentage of phosphorus, around 0.03-0.035% by weight, to imbue these alloys with unique properties such as improved flow, wear resistance, and stiffness. Human blood? They have excellent cold workability, … If it sounds attractive to your application, be sure to contact your supplier, as they will have the newest alloys available. 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. (All compositions mentioned in this article refer to percent by weight.) 1933) on isothermal transformations in steel led to the discovery of a superior microstructure, namely bainite, with improved toughness at a given hardness for typical blade hardnesses (above 40 on the Rockwell C hardness scale). Table 1, below, shows some mechanical properties relevant to phosphor bronze’s uses and strengths. 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. Aye goe forth too ackwire ye dragguns bloood withe witch too finnish Phosphor bronzes have been around for a long time. The CF Martin D-45 Excalibur is the latest design collaboration with renowned inlay artist Harvey Leach. It generally doesn't matter what type of fluid you quench your blade in. 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. Additionally, increased hardness usually comes with increased brittleness, increasing the chances of a blade shattering. Tungsten vs Tungsten Carbide - What's the Difference? However, it isn't achievable in ordinary carbon steel using typical, continuous-cooling quench media. 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. 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. Use Mercury as quenching liquid for swords? 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. Copyright© 2020 Thomas Publishing Company. Phosphorus is one of the most potent solid-solution strengtheners of C54400 Phosphor Bronze. 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. 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). Gibbs stocks gauge ranges from 0.006" - 0.031" I hope this makes sense and is helpful. 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. if it eventually needed real sharpening, it would mean the coating had failed so they'd have to redo the finishing & coating steps. You do not want phosphorus mixed with your steel. You want a thin layer on the outside. Phosphor Bronze is an alloy of copper, containing 3.5 to 10% tin and a phosphorus content of up to 1%. Toughness: Toughness is a measure of how much force a blade can take and still return to is previous shape. This means it can control the temperature the steel is cooled to exactly. Where else can you have a conversation about the practical uses of distilled dragon blood? TThinking back on nit; I *do* have eilxer coateds onnit. If you had Bronze Age tech, phosphor bronze would be excellent sword making stuff. I am a blacksmith. The forces involved when they fight are intense. This equates to better morale and overall greater fierceness of the warriors. Counting seconds also works. resistance. You don't need to rough them up. It achieves this through the cooling rate of the metal. so that it can use them in its scales. 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. It puzzles me why people refer to their guitars as "axes" or "weapons." The alloys typically contain up to 10% tin and up to 0.35% phosphorus. Such materials could be present in dragon's blood especially if parts of the dragon were ground into the blood. It is really easy to overheat or underheat the steel. (9 ksi) while also improving the bake hardening response and deep Consequently, they need many unique adaptations just to avoid bleeding to death or becoming permanently disabled in the course of their frequent scuffles. -, :P and then there are people like this: "I've been using canola oil for quenching my 5160" -. 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. 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. What qualifications are used to consider a sword "better" if it is treated with blood? What is this stamped metal piece that fell out of a new hydraulic shifter? This section will briefly explain each property and show how they make this copper alloy unique. The electrical conductivity of phosphor bronze is about 15% that of pure copper – so why use it in electrical applications when copper is better able to carry electricity? ... D'ADDARIO PHOSPHOR BRONZE ACOUSTIC GUITAR STRINGS, 12's $55 (SUNNYSIDE/DENVER) pic hide this posting restore restore this posting. Slow, and intolerant of cold weather. This may also explain why those darn dragons don't burn themselves so easily : their blood helps dissipate the heat so well! The people understand germ theory, and atoms (though not sub atomics). Worldbuilding Stack Exchange is a question and answer site for writers/artists using science, geography and culture to construct imaginary worlds and settings. 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. @JustinThyme Certainly, so long as it still works as blood. 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. Website Last Modified December 23, 2020. annye othere, beinge unbrakeable, undullable, magicallee sentient annd possess'ed of Dance of Venus (and variations) in TikZ/PGF. familiar example in this category is the classic phenomenon of temper The material: phosphor bronze; the someone: Olin Corporation. Tone Compared: Phosphor Bronze vs 80/20 Bronze. Molten salt is also extremely dangerous. Tougher blades, though, are generally considered better- they snap back better to their original shape and don't become bent as easily. $11.99 $ 11. A thin coating of mercury or arsenic on a blade can dramatically increase the killing effectiveness of the steel. Use MathJax to format equations. Brine cools steel faster than normal water, faster cooling is not good for a sword, it makes steel brittle. Better is more control of the process. Elves, goblins, dragons, magic. You don't have to look much further for this placebo than the Rhino Horn. you can demagnetise it. As mentioned above, 80/20 strings produce a crisp, bright, and projecting tone that many vintage guitar enthusiasts love. 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. Semi-plausible reason why only NERF weaponry will kill invading aliens. 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. Annealing Bronze. Detrimental effects of phosphorus in steel include various forms of +1, What I would have gone for. the faster the cooling the harder the steel. 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. 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. The dust and fumes of phosphor bronze are also toxic when inhaled, so be wary of both your wallet and your lungs. 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. Nowhere said faster than water. Once activated, it quickly consumes the victim since human immune defenses are no match for a virus born in dragons. You are not going to be using dragon blood to add carbon, you can already mine graphite and more importantly make charcoal. You might want to read my answer. But there are solutions. Q: I need to bend a thick piece of bronze, but it is too stiff. Known for its ability to resist stress cracking and fatigue, 544 bronze also offers good formability and excellent machinability. The blade then cools incredibly slowly. 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. Why does 我是长头发 mean "I have long hair" and not "I am long hair"? 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. 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. Elixir Strings Nanoweb Phosphor Bronze Acoustic Guitar Strings -.012-.053 Light .012-.053 Nanoweb Light Gauge Acoustic Guitar Strings, Phosphor Bronze Now, normally this would not be quite what you want for quenching, but Dragons' blood is also magical. So in order to make dragons blood superior for quenching to water, we need to find its one flaw. 80/20 or phosphor bronze strings match the thru-hulls ! Phosphor bronze. $150. @John Dragon blood is not pure phosphorus. https://www.chemistrylearner.com/phosphor-bronze.html, https://www.copper.org/publications/newsletters/innovations/2001/06/phosphor-bronze, https://www.columbiametals.com/files/products/84.pdf, http://www.matweb.com/search/datasheet.aspx?matguid=97d71ced64534f4ba13b763e5f35e0c8, Top Tungsten and Tungsten Carbide Manufacturers and Suppliers in the USA, Different Types of Aluminum Grades (Properties and Uses), 6061 Aluminum vs. 7075 Aluminum - Differences in Properties, Strength and Uses, 6061 Aluminum vs. 5052 Aluminum - Differences in Properties, Strength and Uses, 6061 Aluminum vs. 6063 Aluminum - Differences in Properties, Strength and Uses, 6061 Aluminum vs. 2024 Aluminum - Differences in Properties, Strength and Uses, 3003 Aluminum vs. 6061 Aluminum - Differences in Properties, Strength and Uses, All About 5052 Aluminum (Properties, Strength and Uses), All About 2024 Aluminum (Properties, Strength and Uses), All About 6063 Aluminum (Properties, Strength and Uses), All About 3003 Aluminum (Properties, Strength and Uses), Top Aluminum Suppliers and Manufacturers in the USA, All About 6061 Aluminum (Properties, Strength and Uses), All About 7075 Aluminum (Properties, Strength and Uses), Titanium: Density, Other Characteristics, and Uses.

If it is too strong, it would make it really difficult to sharpen the blade. Company. Boiling point? Dragons are usually big and armored, begging the question of where the square cube law was when they were created. It would be safer for it's wielder to carry than the elementally poisoned blade described above. Second, graphite is an excellent refractory material able to provide stable heat insulation across a wide range of temperatures. https://www.totalmateria.com/page.aspx?ID=CheckArticle&site=kts&NM=211. DO NOT use CA to hold anything in position for soldering. Fiducial marks: Do they need to be a pad or is it okay if I use the top silk layer? The direction of rotation of the vortex is reversed every half-cycle of the oscillation. Their density is around 8.8 g/cm3, and most forms of these alloys respond to hot working, cold working, and heat treatment.
