摘　　要：采用强流脉冲电子束处理对Cu Fe10合金表面进行轰击,通过SEM观察横截面可知实际重熔层厚度。建立了强流脉冲电子束表面改性过程含内热源的非稳态热传导的一维物理模型,采用ANSYS软件对其改性过程中的温度场进行了数值模拟。模拟结果表明,所建立的物理模型与实验结果较为吻合。The surface of Cu Fe10 alloy was irradiated by high current pulsed electron beam. The thickness of remelting layer was observed by SEM. One-dimensional unsteady heat conduction physical model of high current pulsed electron beam surface modification process was built. By using ANSYS software, the temperature field of high current pulsed electron beam surface modification process was simulated. The simulation results indicate that the established physical model is coincident well with experimental data.
