摘　　要：Ｃｒ１２ＭｏＶ钢经渗碳等温淬火，渗层和心部组织中的残余奥氏体已占较大比例，但这两区域的γ＇数量变化规律相反，反映了该区域成分和组织变化的特殊性，从而构成高碳高合金钢ＣＤ渗碳等温淬火组织的一个重要研究方面。s a high carbon content and high alloy element alloy steel, Cr 12 MoV steel has been carburized fol-lowed by austemporing.There is a relatively large quantity of retained A both in the inside structure and surface layer, but the quantity of retained A in these two positions change.in reverse pattern.This is caused by speciality of phase and composition in these two parts. The study on retained A is a important aspect in the structure of CD carburizing followed by austempering in high carbon and high alloy element alloy steel.
