中文摘要:
      研究用浸渗法制备颗粒增强铝硅复合材料的工艺。采用加压渗流将铝液压入到硅颗粒间隙中制备复合材料，分析了不同粒度颗粒增强相对复合材料浸渗长度及Si含量的影响。结果表明：利用浸渗法制得的Al-Si复合材料硅的体积分数可高达60%以上，随颗粒度的减小而增加。
英文摘要:
      The process of preparing silicon particle reinforced aluminum matrix composites by impregnation method was studied. Aluminum alloy was pressed in the clearance of Si particle by compressive infiltration to prepare composites. The effects of different particle sizes on the alumetizing length of precast block and the content of Si were analyzed. The result indicates that the content of silicon in composites can reach to 60% in the Al-Si composites by the impregnation method, and the content of Si is increased as the granularity decrease.
