Martensitic Transformations in Stainless Steels

open access: yesProgress in Physics of Metals, 2022
Currently, the direction of materials’ research, in which the martensitic transformations are observed, is intensively developed. This is due to the fact that, in the martensitic-transformation process, various defects of crystal structure (twins, dislocations, packaging defects, etc.) are formed in many materials, which together with grain ...
