Modeling the Effect of Stress and Plastic Strain on Martensite Transformation

Abstract:

Article Preview

The influence of compressive stress up to 250 MPa and plastic deformation of austenite on the martensite transformation behavior of a eutectoid steel is studied both experimentally and theoretically. It is demonstrated that martensite formation is assisted by stress but it is retarded when transformation occurs from plastically deformed austenite. With the quantitative modeling of the problem based on the theory of displacive shear transformation, the explanation of contradicting observations is presented.
