摘　　要：为解决传统物理工艺试验在预测超快激光加工过程中材料发生液相爆炸方面的局限性,开发了基于MATLAB的超快激光加工温度预测程序,程序结合双温方程模型、有限差分法以及材料热物理属性与激光工艺参数,实现了对加工过程中材料电子与晶格温度变化的精确模拟。为验证程序的预测能力,选取铜材料进行了实际加工试验,并将试验结果与程序预测结果进行了对比分析。结果表明,程序能准确预测加工过程中材料电子与晶格温度的变化趋势,并在特定条件下判断液相爆炸的发生,验证了其在实际应用中的可行性和可靠性。In order to solve the limitation of traditional physical process test in predicting liquid phase explosion of materials during ultrafast laser processing,a temperature prediction program for ultrafast laser processing based on MATLAB was developed.The program combines the twotemperature model,the finite difference method,and the thermophysical properties of materials and laser processing parameters to achieve precise simulation of the electron and lattice temperature changeing during the processing.In order to verify the predictive ability of the program,copper material was selected for actual processing test,and the test results were compared with the predicted results of the program.The results showed that the program could accurately predict the change trend of electron and lattice temperature of the material during processing,and judge the occurrence of liquid phase explosion under certain conditions,which verified the feasibility and reliability of the program in practical application.
