The Effects of Heat Treatment and Deformation on the Martensitic Transformation of FeMn (Cr) Steels

Abstract:

The ε martensite phase was investigated in three types of FeMn (Cr) steels by means of metallographic, EBSD and XRD methods as well as by dilatometric and DSC examinations during heating and cooling. In the course of the latter examinations, the transformation temperatures (Ms, A_s) of ε martensite were determined in the previously deformed samples as well. The results were also compared to the thermodynamic data published in the references describing the γε and γα transformations.
