Transformation Plasticity of Hot-Die Steel During Hardening

Abstract

The paper presents the results of investigations of transformation plasticity of hot-die steel (high temperature–resistant steel used in high-temperature deforming) during hardening. A special device was used to evaluate transformation plasticity and determine the maximum normal bending stress, modulus of transformation plasticity for medium alloyed and medium carbon steel.
