Methodological approaches to the study of reverse martensitic transformation in metastable austenitic steels

Methodological aspects of the high-resolution dilatometry analysis of the reverse α→γ-transformation in cold-worked metastable austenitic steel Fe-0.07C-18.7Cr-9.2Ni-0.6Ti-1.1Mn-0.4Si (wt.%) were considered. It was shown that the reverse α→γ-transformation occurs in the temperature range from AS=520 °C to AF=920 °C. Two consecutive stages corresponding to shear and diffusion transformations were reveale
