摘　　要：结合材料在温度变化过程中热物理性参数的变化,利用ANSYS软件对液-固双金属复合铸造过程中界面的温度场进行模拟,得到了复合界面的温度及分布随时间变化的关系。从而有效地预测了复合层是否达到完全冶金结合以及复合层中缩孔、缩松等缺陷出现的可能性及位置,为优化液-固双金属复合铸造工艺方案提供了科学指导。Combining with the variety of the nonlinear thermophysics parameters in the mutative temperature process of material, temperature field in the interface of Liquid-Solid bimetal composite casting was simulated by ANSYS software. The temperature of interface and the relationship between temperature and time was obtained. This method can forecast whether it is complete metallurgic combination and the possibility and location of arisen disfigurement such as shrinkage, shrinkage porosity. It provides scientific guidance for optimize technical scheme in Liquid-Solid bimetal composite casting.
