【Abstract】 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.更多还原
