APPLIED PROBLEMS OF STRENGTH AND PLASTICITY

Abstract

The effect of alloying elements on the hardening during hot deformation of stable and supercooled austenite in die steels of two alloying system, namely, Cr–Ni–Co–Mo–V and Cr–Ni–Mo–V–Mn, has been studied. The alloying elements that most significantly influence the strain hardening of austenite at temperatures 400–800°C have been determined.

Keywords:

hot-pressing steels steels with controllable austenitic transformation during operation alloying elements austenite strain hardening hot strain hardening
