| 摘 要： | 本文作者采用挤压铸造法,制取了硼酸铝晶须增强Al基复合材料,并根据Laplace方程及多孔体的渗流物理基本原理,从多孔渗流动力学角度分析了挤压浸渗过程中金属液在多孔体中的流动,认为紊流才是其主要的表现形式。并较详细地分析了晶须长度对预制件孔结构及浸渗的影响。

| Abstract: | AlBO W whisker Al matrix composites were fabricated by squeeze casting technique. First, according to the basic principle of fluid dynamics in porous media and Laplace equation, the squeeze casting infiltration process of metal melt fluid in the porous whisker preform was analyzed. The paper indicated that metal melt fluids infiltrated the whisker preform by a disordered fluid status. And then, the effect of the length of whisker on the void structure of the porous preform was analyzed in detail. |
