摘要

研究了点缺陷对奥氏体铬镍钢马氏体相变行为的影响。用同步辐射衍射法研究了材料的塑性变形。给出了用分子动力学方法得到的结果。这些数据被用来考虑点缺陷的出现过程和合金元素在塑性变形条件下的偏析倾向。结果表明，摩擦加载伴随着奥氏体向马氏体的转变和扩散散射程度的增加。根据变形过程的模拟，摩擦产生合金元素的偏析，降低了奥氏体的稳定性，是参与研究钢中马氏体转变发展的一个因素。

Analysis of Austenite Stability Under Conditions of Plastic Deformation

The effect of point defects on the behavior of martensitic transformation in an austenitic chromium-nickel steel is investigated. The plastically deformed material is studied using the synchrotron radiation diffraction method. Results obtained by the method of molecular dynamics are presented. The data are used to consider the process of the appearance of point defects and the tendency to segregation of alloying elements under conditions of plastic deformation. It is shown that frictional loading is accompanied by an austenite-to-martensite transformation and increase in the degree of diffuse scattering. In accordance with the simulation of the deformation process, friction produces segregations of alloying elements, which lowers the stability of the austenite and is a factor participating in the development of martensitic transformation in the steel studied.
