研究了高增强相含量Al/Si复合材料压力熔渗法制备工艺,复合材料内的自由孔隙和硅颗粒的分布均匀,同时研究了Al/Si复合材料的特性和断裂行为,通过金相组织分析和断口观察表明,复合材料的断裂行为主要是由于硅颗粒的脆裂性而引起的,并且由此向材料内部延伸最后导致复合材料断裂失效;特别研究了复合材料在高精度热机械分析仪下的热膨胀行为,实验得出Al/Si复合材料的平均线性热膨胀系数在(8~10)×10-6/℃范围内,并随着硅含量的增加而降低;实验基于Turner的模型进行,实验测得Al/Si复合材料的热膨胀系数与理论计算值的存在差别,这是由于理论模型没有考虑材料制备过程中粉末形状,粒度、第二相颗粒不可避免的不均匀分布,孔隙度以及剪切应力对热膨胀性能的影响,其结果与预测相符合。
