NUMERICAL ANALYSIS AND TECHNICAL PARAMETER OPTIMIZATION SYSTEM OF LASER TRANSFORMATION HARDENING PROCESS

Zhang Liwen, Pei Jibin, Chen Feixia, Zhang Guoliang Department of Material Engineering, Dalian University of Technology, Dalian 116023  
The data-bases of thermal physical property and laser transformation hardening processing parameter for various kinds of steels can be set up using this system. The heat transfer model during laser transformation hardening process has been set up. The temperature field and structure field during laser transformation hardening process were calculated using finite element method and finite difference method. The calculated temperature field and structure field can be displayed by graph. The calculated widths and depths of laser transformation hardening zones are in good agreement with the experimental results. These results provide a basis for technical parameter optimization.
