诚实说‘那些我不知道的东西’
阿拉总是诚实说那些阿拉不知道东西，比如M54钢，知道是当今世界最强钢材，综合性能最优异的，因为电子战飞机上航母，这家伙很重，起落架在甲板上给礅折了，哈，国防部掏银子研制的，再就是知道这是纯理论设计的材料，由玩材料的基尼提出，计算机模拟，很短时间就玩好了，这就是海雕速度，用的什么钮？阿拉没见过了，没按过，阿哈哈，但肯定，有个钮，
世界就是这么复杂，他不给你钮？你怎么办？假如中国的非标自动化没有钮了，大家还吃馒头吗？哈哈
998前辈，如果去自主研发的非标外企，有前途吗 https://www.questek.com/ferrium-m54.html
“Ferrium M54 (AMS 6516; MMPDS-09) is an ultra-high strength and high fracture toughness steel with excellent fatigue resistance and high resistance to stress corrosion cracking (SCC).
M54 steel is one of the strongest and toughest steels in the world.
QuesTek designed M54 steel using Integrated Computational Materials Engineering (ICME) technologies under Navy SBIR funding to be a cost-effective alternative for AerMet®100 (AMS 6532).
M54 steel is double vacuum melted (i.e., vacuum induction melted and then vacuum arc remelted or "VIM/VAR") for high purity, leading to much greater fatigue strength.”

“Design and Development Background
In December, 2013, M54 steel was approved for inclusion with A- and B-basis minimum design allowables in the Metallic Materials Properties Development and Standardization (MMPDS)-09.
In July 2012 we announced a NAVAIR-funded SBIR Phase II contract to demonstrate M54 steel for use in U.S. Navy aircraft tailhooks.
In June 2012 S-basis design allowables for M54 were approved for use in the MMPDS handbook.
In June 2012 a formal machining study of M54 steel was completed, results of which were approved for release in 2013. Results indicate that in general M54 steel machines faster than AMS 6532 for major material removal turning operations.
In 2011 SAE International issued AMS 6516 specification for M54 steel.
In 2011 we co-authored a technical paper that evaluated protection schemes for ultrahigh-strength steels (including M54 steel) for landing gear applications. The paper concluded that a cadmium, chromate, primer and paint protection scheme on M54 steel did not show as much evidence of breakdown as the same scheme on either 300M or 4340 after 500 hours of salt fog testing per ASTM B117; comparative data for zinc-nickel protection performance was also presented (see below).
In 2011 we completed a NAVAIR-funded SBIR Phase II program to further design and develop M54 steel as a lower-cost, high-performance landing gear steel.
In 2011 we completed a NAVAIR-funded SBIR Phase I program that evaluated M54 steel as a material for use in tailhook components, used to abruptly arrest and stop aircraft landing on aircraft carriers.
In 2010 we announced that Latrobe Specialty Steel Co. (now Carpenter Technology) is the initial firm licensed to commercially produce and sell M54 steel.” "QuesTek was established in 1996 by four individuals affiliated with Northwestern University (of Evanston, IL, USA) to commercialize Prof. Gregory B. Olson’s pioneering academic work in the field of computational materials design." "Greg Olson, Sc.D.
