摘要

In the present work, atomic force microscopy (AFM) and electron backscatter diffraction (EBSD) analyses are used to study the microstructure of metastable AISI 321 austenitic steel subjected to quasi-static uniaxial tension in the temperature range 213–338 K. The influence of deformation on phase transformations in metastable austenitic steels is shown. The temperature dependence of the volume fraction of the martensitic phase and microhardness are revealed.
