It seems beyond unlikely that OP isn’t a retread.
For the record OP “know it all” people, that actually know nothing, and do nothing but argue and insult actual SME’s are the reason less of them post here. |

I'm interested in the science/engineering of firearms, automobiles, aero etc in general like a lot of us are and always looking for the next best thing to "make it better." I watched some YouTube videos of people torture testing their AR's and AK's and the only gun I saw survive the test of 2,300+ rounds of full auto was the POF P416 from Iraqveteran8888. It seemed in those videos the barrel was the weakest link and heat was the culprit. Also, the links of Battlefield Las Vegas here at this forum on reading about guns with 200,000 rounds fired through them got me thinking on ways to increase the lifespan and longevity of firearms that are put through extreme abuse. I Googled up "Heat resistant steel alloys" and first link I saw this... https://www.hpalloy.com/Alloys/hightemperature.aspx HASTELLOY ® Alloy X (HX) (UNS N06002) Ni 47.5, Cr 21.8, Fe 18.5, Mo 9.0 "Excellent high temperature strength and oxidation resistance to 2200°F. Excellent forming and welding characteristics. Resistance to oxidizing, reducing, and neutral atmospheres. Resistant to SCC in petrochemical applications. Good ductility after prolonged service temperatures of 1200, through 1600°F for 16,000 hours. Gas turbine combustion cans and ducting, heat-treating equipment, spray bars, flame holders, furnace rolls, furnace baffles, and flash drier components." Hastelloy X is a nickel-chromium-iron-molybdenum superalloy with outstanding high temperature strength, oxidation resistance, and fabricability. Alloy X’s oxidation resistance is excellent up to 2200° F... http://megamex.com/hastelloy_x.htm Could that some day be used in firearms like barrels for fully automatic fire for prolonged periods of time? Also, your opinions on lithium alloys 2055 and 2099 for receivers compared to 7075 T6. View Quote Stuff was super thin sheet metal and super duper pricey. I can't imagine what a bar of that shit costs. |

Quoted: Probably not the same place but I remember doing a couple test shots like that for DoD. We were supplied with a piece of metal 12"x12"x1" and told that they wanted it bonded to some grade III Ti with no interlayer. They wouldnt say what it was or really give the engineers any specs for it other than hardness, ductility/heat info. We ended up doing a "hot shot" with it, it got put it in the heat treat oven and the rest of the shot was set up out in the site. It was removed from the oven, raced out to the site in a pickup, set, and shot within 2 minutes. It somewhat stuck to the Ti, but the bond was shit and it shattered like a safety glass window. Whatever it was could not take the pressures and angles involved. .Gov still paid though View Quote |

Not my project but has similarities. We had to produce a big piece. 72x36x0.5 finished. It was all experimental. Like your example, the plate shattered like glass when shot and the bond attained was never very good. It was a total failure but I got paid. All I really did was subcontract everything.

Those super alloys aren't necessarily good in every possible role. Steel is quite good in many applications. Even if it is inferior in certain ways to other metals, steel is still the best all around metal for many different applications. The harder a metal is the more brittle it is. There is no wonder metal that is as resilient as steel (ie different alloys give so they don't crack as fast due to repeated exposure to violent forces), as hard and wear resistant as inconel, etc.
