摘要 本文提出一种包含相变及表面吸收系数随温度变化的激光与金属材料相互热作用的半解析计算方法,并以含固液相变但未发生传质的热传导研究为例,给出计算实例。 In this paper, a semi - analytical method is developed to calculate the temperature field in the laser heat treatment of metal, in which the effects of phase transition and temperature-dependent absorptivity are considered. The calculating example has been accomplished for the case that the solid - liquid transition takes place without the mass transfer.
