摘要

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.
