仪表制造工业的发展,对弹性敏感元件用的材料要求更加严苛,要求这种材料应当具备与弹性性能相配合的热稳定性以及特别是在浓硝酸的氧化介质中耐腐蚀等良好的综合性能。弥散硬化合金70合金最适合这种要求,这种合金具有高的宏观和微观塑性变形抗力,以及热稳定度迭500～550℃,也就是与耐热性能比较好的镍基和 The development of the instrumentation manufacturing industry requires more stringent material requirements for elastomeric-sensitive components, requiring that such materials should have good overall performance in combination with thermal stability and with corrosion resistance, particularly in concentrated nitric acid oxidation media . Dispersion hardened alloy 70 alloy best suited to this requirement, this alloy has high macroscopic and micro-plastic deformation resistance, and thermal stability Diego 500 ~ 550 ℃, which is better with the heat resistance of nickel-based and
