摘　　要：为了揭示强流脉冲离子束辐照材料表面的热效应,用有限元方法建立了强流脉冲离子束辐照金属表面的传热模型,以铬镍钢(17-19Cr/9-13N i)为靶材,对不同载荷和边界条件下的热效应进行模拟,分析了靶材在不同条件下加热和冷却的效应,给出了铬镍钢在辐照后内部温度分布、状态变化以及温度变化速率.In order to study the thermal effect on metal surface irradiated by high intensity pulsed ion beams （ HIPIB）, a model of heat transfer is set up by finite element method. The thermal effect on surface of 17- 19Cr/9-13Ni steel in different loads and boundary conditions is simulated by analyzing the different effects of heating and cooling steps at different conditions. It has been shown that it has different temperature distribution, rate of temperature variation and state transformation of irradiated metal under different conditions.
