A new numerical approach for heat conduction and phase transformation analysis of laser surface hardening

Abstract

A large number of machine components which based on steel or metal require a combination of properties of high surface hardness along with good toughness and wear resistance due to severe conditions of high-stressed located on their surface, which is usually not possible in a conventional heat treatment method. Laser surface hardening as one of the heat treatment methods has become the most appropriately method to increase the wear resistance, toughness and hardness of the material's surface without affecting the bulk material.
