摘　　要：总结近年来关于液态成型液流在预制型浸渗过程中行为的研究 ;在描述金属液流在预制型孔隙内的流动时 ,讨论液流在预制型的浸渗速度、最小浸渗压力以及其他因素的影响。讨论结果表明 ,液态金属在纤维中的浸渗充填过程是各种阻力与浸渗压力共同作用的结果。增强体的体积分数愈大 ,直径愈小 ,需要施加的浸渗压力就愈大。This paper deals with infiltration of liquid alloy in preform during formation of Metal Matrix Composites and discusses the effect of infiltrating rate, minimum pressure and other factors on the liquid flow in perform. Discussion results show that infiltration of liquid metal into fibers relies on various obstructions and force of infiltration. Practice shows that the larger the volume fraction of preform and smaller the diameter of hole in perform, the bigger the infiltration pressure.
