摘要
本文通过２０Ｃｒ２Ｍｎ２Ｍｏ钢组织遗传的研究表明，该钢的非平衡组织，经一次加热淬火可以产生组织遗传。但在二次加热奥氏体化过程中，在Ａ(ｃ１)－Ａ(ｃ３)区的低温侧，有利于形成针状奥氏体；在其高温侧易形成粒状奥氏体。它们虽然都可以导致组织遗传，而在实际生产条件下，产生的组织遗传，则是针状奥氏体形成长大合并的结果。
In this paper, structure heredity in 20Cr2 Mn2 Mo steel has been investigated. It is concluded that the nonequilibium stucture heated and quenched for two times gives rise to the structure heredity. But, in the course of the second austenization,it is subjected to form needle austenite at low temperature of Ac1 - Ac3 , and granular austenite at higher temperature Althaugh thetwo structure lead to structure heredity, only the granular austenite is main reason of structure heredity in the practical productioncondition.
