Abstract

This paper is based on theory of extended Landau phase transformation, consider achievement of A. F. Devenshire and F. Falk et al, and combines with characteristics of martensitic transformation, the research of effect of applied stress on martensitic transformation during course of laser phase transformation hardening, has been in progress, and a functional analysis expression of Gibbs free energy, which applies to describe the concrete problem, has put forward and discussed. In the paper, the various law of laser phase transformation hardening layer of 45# steel under action of applied stress is studied. The conclusion shows that theoretical analysis are in accord with experimental results.
