强流脉冲电子束表面改性过程具有非稳态、有内热源的温度场特点,利用ANSYS软件对其温度场进行了数值模拟。以纯镁板材为实验材料,采用强流脉冲电子束装置对试样表面进行了脉冲次数为10次的辐照处理。建立了强流脉冲电子束表面改性过程内热源的一维物理模型,并在实验和理论基础上对电子束改性过程中的温度场演化进行了数值模拟。模拟结果显示,所建立的物理模型与实验结果较为吻合。

High current pulsed electron beam (HCPEB) surface modification processisn on steady state temperature field with internal heat source, ANSYS software was applied to simulate the temperature field. Pure magnesium was used as experimental materials, and HCPEB device was used to carry out 10 times pulse irradiation on the sample surface. One dimensional heat source physical model of HCPEB surface modification process was established. And on the basis of experimental and theoretical, numerical simulation of the temperature field evolution during electron beam modification was carried out. Simulation results show that physical model is consistent with experimental results.
