Effect of Alloying Elements on the Hardening of Die Steels in the Austenitic State during High-Temperature Plastic Deformation

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.
