本文结合自己的工作综述了残余奥氏体(A_R)含量、分布及稳定性等对接触疲劳性能的影响。认为对于不同的钢种、不伺的组织状态和不同的服役条件,残余奥氏体应有一个适当的含量和适当的稳定性,在某些钢中超细晶团的形成对接触性能的影响起着决定性的作用,过份强调细小碳化物的作用是不适宜的。为了深入了解A_R行为.A_R变化的单因素化是个重要条件。 In this paper, the author summarizes the influence of residual austenite (A_R) content, distribution and stability on the contact fatigue performance. It is believed that residual austenite should have an appropriate content and appropriate stability for different steels, unorganized structures, and service conditions, and the effect of ultrafine graining on the contact properties in some steels Plays a decisive role, too much emphasis on the role of small carbides is not appropriate. In order to gain insight into A_R behavior, univariate changes in A_R are an important condition.
