Abstract

The method adding electromagnetic field during laser heat treatment is a new heat treatment method that expend application expansion of laser heat treatment. In this paper, based on thermal non-elasticity, principle of metal phase transformation, deformation thermodynamics and theory of electromagnetic field and using the internal variable method of continuous medium mechanics, the heat conduction equation with magnetic-field phase transformation during laser heat treatment has been inferred. The equation and its theoretical method is the basis to study the theory and experiment of laser magnetic quenching and also the basis to study further on the material structure distribution and properties. And also by means of the equation, has the numerical analysis on temperature field in the course of laser magnetic quenching been in progress.
