摘 要：The aim of this paper is to introduce the application and future of computer simulation in heat treatment process, as an important method in manufacturing of material. Here, developments of the finite element based on a code "HEARTS will are presented by using some experiments to be applied simulation of general quenching, quenching-tempering and quenching with carbonization or induction. The code "HEARTS" for 3-D simulation of heat treatment process based on a metallo-thermo-mechanical theory is presented. Coupled equations of heat conduction, inelastic stresses and kinetics of phase transformations are derived as well as the diffusion equation during carbonization, followed by finite element formulation. The program is available for 2-D and 3-D simulation of various heat treatment processes, such as quenching,tempering and so on. The system is used in the CAE environment of some pre-and post-processors over "Ⅰ-DEAS ", "PATRAN" or "FEMAP". Some examples of simulated results of carbonized quenching processes for cylindrical rod, ring and gear wheel are also presented.
