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. Animals run on ATP which is a high energy phosphorus compound and so all blood has a lot of phosphorus. 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? Bats blood? Dragon blood is just a non-flammable liquid with thermal conductivity similar to oils or water but unlike water and oils it has a vapor point higher than steel's melting point, so the oil can be heated to much higher temperatures. (9 ksi) while also improving the bake hardening response and deep When stored in the structure of cold steel, the microscopic life lays dormant until revived by hot human blood. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Even oils cool too quickly for ideal results, there is no upside to cooling faster. 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 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. Well cooling metal too slowly results in it being too soft but cooling it too fast results in it being hard but brittle. DO NOT use CA to hold anything in position for soldering. Privacy Statement and This standard material is given a machinability score of 100%, meaning it is easy to machine and causes little problems in the shop. The direction of rotation of the vortex is reversed every half-cycle of the oscillation. This of course assumes that the blood swords are forged to a high quality per James' answer. 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. Nurmenfnograth was never seen again, and the only clue as to his fate was a brief and cryptic inscription found scratched into the bare rock next to the book in the Ryunes Of Gnobrathmingfnorp, which translates rather loosely as. By using this site, you agree to our. But there are solutions. Use Mercury as quenching liquid for swords?

Actually pretty bad, since people whose blood is being used to quench the sword are obviously LOSERS! What tone to play for an upper neighbor in jazz? Thank you :). A thin coating of mercury or arsenic on a blade can dramatically increase the killing effectiveness of the steel. embrittlement... making a blade that is perfectly aligned and well hardened, and then gilded with arsenic making it poisonous to any who are stabbed by it. Only about 3 to return it to working temperature while working it. Are all satellites of all planets in the same plane? Although I was thinking along the lines of the blood actually boiling. Most alloys form an attractive patina in the presence of oxygen and are therefore also useful for decorative applications. Snakes blood? Materials for Engineers and Technicians, 4th-2006_(Raymond A. Higgins).pdf pages: 415 It possesses a timbre similar to that of a snare with a handcrafted wood shell. https://www.totalmateria.com/page.aspx?ID=CheckArticle&site=kts&NM=211. Dance of Venus (and variations) in TikZ/PGF. 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. Gibbs stocks Grade A phosphor bronze in spring temper (8#'s hard) in the B 92-98 Rockwell range. Company. Semi-plausible reason why only NERF weaponry will kill invading aliens. Thomas Register® and Hardness: Hardness is a measure of how much force it takes to deform the steel. ... D'ADDARIO PHOSPHOR BRONZE ACOUSTIC GUITAR STRINGS, 12's $55 (SUNNYSIDE/DENVER) pic hide this posting restore restore this posting. Acidic? 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. This banner text can have markup.. web; books; video; audio; software; images; Toggle navigation And if the coating is too thin, sharpening would just take it off. Toughness: Toughness is a measure of how much force a blade can take and still return to is previous shape. For example, bringing a cold 1/4" round bronze brazing rod to working temperature in my forge takes about 10-12 blower turns. 99. And it is not a magical benefit, dragon's blood swords are still better without any detectable powers or while in an anti-magic zone. By clicking “Post Your Answer”, you agree to our terms of service, privacy policy and cookie policy. Now go deeper than just a thin coating... Perhaps quenching a scalding hot blade in poisonous metals saturates the resulting steel with a lethality which can't just be wiped away. 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. 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. 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.

Enlist Your Company ico-arrow-default-right. I hope this makes sense and is helpful. What is the relation between a priori and tautologies? As material sciences advance we notice that molecularly perfect substances often exibit extreme proporties, so we can only assume that Dragons have evolved to create many of these materials to strengthen themselves and make them able to support their own weight. Use MathJax to format equations. 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. Rhinoceros blood? Can you improve on your regular sword by sticking it into a dragon? Are dragons common enough that you can maintain a workable supply of the stuff? It even makes sense that dragons would have such blood since they need blood that will not boil no matter how hot they are. It only takes a minute to sign up. The tin increases the corrosion resistance and strength of the alloy. This section will briefly explain each property and show how they make this copper alloy unique. .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: 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. While history is always good to have, when it comes down it, what matters most in the phosphor bronze vs 80/20 bronze debate is how they sound, and how they feel. Online description: Phosphor Bronze delivers the widest range of sound of any Black Panther snare. 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.

Visit us Today! Slow, and intolerant of cold weather. 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. So in order to make dragons blood superior for quenching to water, we need to find its one flaw. Phosphor bronze is an alloy of copper with 0.5–11% of tin and Feel free to join me in there. Phosphor bronze bars are stocked in diameters ranging from ½ inch up to 2 ½ inches, that can also be tailor cut in length to cater to your exact requirements. 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. Thanks for contributing an answer to Worldbuilding Stack Exchange! You don't have to look much further for this placebo than the Rhino Horn. and stiffness of the alloy. The problem is, it is a very thin layer, and depending on the type of steel may actually flake off. 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. This causes phosphor bronze to be both useful for shaping operations and more difficult to machine, but more on this in a bit. They are most often used for corrosion-resistant applications, as well as in other applications that need a springy-yet-durable material. 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. OK so anyway. so that it can use them in its scales. Damascan steel managed to get very strong and still elastic through nanowires and carbon Nanotubes that were enclosed in the metal. 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. Graphite is a blacksmith's friend for three reasons. @John Dragon blood is not pure phosphorus. All Rights Reserved. Would France and other EU countries have been able to block freight traffic from the UK if the UK was still in the EU? 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. 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. improve machining characteristics and atmospheric corrosion We will first examine the composition of phosphor bronze, and then discuss its strengths, drawbacks, mechanical properties, and finally common applications of such a useful metal. 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 addition of lead will make phosphor bronzes stronger and more machinable, but unleaded phosphor bronzes are also strong and resistant by themselves. You do not want phosphorus mixed with your steel. Counting seconds also works. 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. 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. To subscribe to this RSS feed, copy and paste this URL into your RSS reader. Quenching is not even the final step in the heat treating process. Tougher blades, though, are generally considered better- they snap back better to their original shape and don't become bent as easily. dragon blood has evolved to do this. The entire book was found in a rather scorched-around-the-edges condition outside of The Great Smoking Cave. Second, graphite is an excellent refractory material able to provide stable heat insulation across a wide range of temperatures. It would be safer for it's wielder to carry than the elementally poisoned blade described above. Dragons' blood is an absurdly good insulator. Phosphor bronze is an alloy of copper with 0.5–11% of tin and 0.01–0.35% phosphorus. 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. Bronze has come a long way from just being an alloy of copper and tin; it is now a broader class of copper alloys that are still finding new uses to this day. This material is usually used to make springs and bolts, as well as similar items. Today we can use molten salts for some of these, but that is a recent invention. It can even be used for annealing and tempering much how modern smiths use ovens. It could be beneficial if it has the right properties. What physical properties could dragon's blood possess, that would somehow make it better for heat treating blades? To do this you first harden the blade by quenching it as mentioned. I really love worldbuilding. Additionally, cooling some metal quickly enough can result in it being amorphous. The blood of your dragons is a high-boiling liquid (very low vapor pressure) with excellent thermal stability, excellent thermal conductivity, and a high specific heat capacity, making it ideal for austempering a blade as it will not boil off, decompose, react with the blade, or change in temperature much when the part is added, while drawing heat out of the part quickly to bypass the "nose" of the curve for that steel. drawability... Phosphorus is also used as an additive in steels to 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. Can be sharpened to a narrower edge and hold it better without becoming brittle. In our selection you can also find bows, shields, helmets, armor, clothing and other items fit for any warrior from the past. Bronze vs. Brass - What's the Difference? embrittlement which reduce the toughness and ductility. None of The Wise who have been consulted regarding this matter can explain quite what this inscription means. It resists wear, stress and marine corrosion, and can be polished to a rich, golden shine. Thomasnet Is A Registered Trademark Of Thomas Publishing Are we free to alter the chemical composition of dragons' blood to whatever we need it to be? All About Aluminum Bronze - Strength, Properties and Uses. I got this idea because I thought I had read that the druids did exactly this with swords and human blood - quenched them in blood to harden the outside, which was accomplished by the high phosphorus content of blood. 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. Something about the body temperature of a person, plus the saline content allowed for just the right speed of blade temperature decrease. Why would that be? 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. This special edition guitar is adorned with original artwork in honor of the mythical dragon told to have hidden the mystical Excalibur sword in its tail. When combined with its good spring characteristics, this creates an alloy that is strong and will stay strong. @Bewilderer Any improvement without a noticeable detriment. TThinking back on nit; I *do* have eilxer coateds onnit. 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. 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 can be bought with increased lead levels that will remove its machining difficulty, as it becomes more self-lubricating. The dust and fumes of phosphor bronze are also toxic when inhaled, so be wary of both your wallet and your lungs. Where else can you have a conversation about the practical uses of distilled dragon blood? OK first things first, there is a lot of disinformation in here...first I will address that. Austempering really seems to be the only realistic option. how vim makes the difference for "i" between the insert mode and the inner word. We have a great online selection at the lowest prices with Fast & Free shipping on many items! Quenching a blade in Dragons' blood is not like a normal quenching - it's more like aging a whiskey. The alloys typically contain up to 10% tin and up to 0.35% phosphorus. One fist of dragon's blood for every twelve fists of molten iron has been found to be the ideal ratio for the hardest "dragon steel". Dragons are fierce creatures the size of small commercial jets. Sadly, with science...it doesn't. Perhaps the dragon's blood contains a voracious infection which thrives in the scalding bloodstreams of dragons. Specifications Met: ASTM B139. The people understand germ theory, and atoms (though not sub atomics). For instance, making it more caustic? 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 work of Bain and Davenport at US Steel in the 1920s and 1930s (pat. Website Last Modified December 23, 2020. Better is more control of the process. First, being elemental carbon, it can be used in the production of weapon-grade steel. 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. Detrimental effects of phosphorus in steel include various forms of In your case, though, you can do better.
