Numerical Simulation of the Mechanical properties of 40Cr Steel During laser Quenching

摘要

Based on the theory of phase transformation, computational mechanics, thermal non-elasticity and the character of laser phase transformation, a non-linear heat conduction equation considering phase transformation and a model of the relationship between the phase transformation products and the properties of 40Cr steel are established and solved by means of Finite Element Method (F.E.M). Comparing the calculated results with those of experiments, satisfying agreement is found. It might be valuable for some practical applications and for the development of theory.
