关于奥氏体的稳定化问题,早巳被人注意,后来又有许多人作了不少的研究,可是到现在还沒有得到一个统一的理论.由于许多细微的条件不能严格地加以控制,甚至试验的重复性都不太好,这也充分说明了奥氏体稳定化的复杂性.衡量奥氏体稳定化的标准普通有两个:一个是在固定条件下当马氏体转变完毕后衡量残留奥氏体的量;另一个是经过稳定化后测定马氏体继续转变温度的降低.在本
As for the stabilization of austenite, it has long been noticed that many people have done a lot of research in the past, but until now no unified theory has been obtained. Because many subtle conditions can not be strictly controlled, or even The reproducibility of the test is not very good, which fully illustrates the complexity of austenite stabilization.There are two common criteria for the stabilization of austenite: one is the measurement after the martensitic transformation is completed under fixed conditions The amount of retained austenite; the other is determined by the stabilization of the martensite to continue the transformation of the temperature reduction in this
