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 L aplace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。
AlBOw whisker Al matrix composites were fabricated by the squeeze casting technique. First, according to the basic principle of fluid dynamics in porous media and the 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 in a disordered fluid status. And then, the effect of the whisker length on the void structure of the porous preform was analyzed in detail. ZL101 is used as the raw material of the matrix for AlBOw whisker reinforced Al composites.
