论述了超细化马氏体板条,共格沉淀新强化相(Laves相),M2C碳化物和残余—逆转变奥氏体向马氏体相变诱发塑性等强韧化机理,用超纯洁熔炼、超均匀化及控制相变等工艺,获得一种低碳-14Cr-12Co-5Mo-Me新型超高强度、高塑性、高韧性不锈钢。
The new strength-toughen mechanisms, such as super fine Martensitic laths, new strength phases, Laves phase and M2C carbide, precipitated coherence with Martensitic matrix and the VIM + VAR double vacuum melting with super pureness, super homogenization hotwork, controlled Martensite transformation heat treatment techniques have been investigated. By means of them a new type of low carbon stainless steel, 14Cr-12Co-5Mo-Me, with ultra-high strength, high plasticity and high toughness was obtained.
