【摘要】研究20Cr2Mn2MoA组织遗传的形核规律,结果表明:20Cr2Mn2MoA在二次淬火慢速加热时发生粗晶组织遗传是通过针状奥氏体的形成、合并而形成的。更多还原

【Abstract】 In this paper , law of structure heredity in 20Cr 2Mn 2MoA steel has been investigated. It is concluded that coarse grain heredity structure is formed by consolidation of γ a when 20Cr 2Mn 2MoA is slowly heated in second quenching.更多还原
