摘要
本文采用冷热循环法测试SiCp／Al复合材料的尺寸稳定性，分析了不同因素对复合材料尺寸稳定性的影响，并探讨了复合材料尺寸稳定性的影响机理。研究表明SiCp／Al复合材料中增强颗粒形状越规则，尺寸稳定性越好；颗粒粒径越大，尺寸稳定性越好；冷却速度越慢，尺寸稳定性越好。热残余应力的和是影响复合材料尺寸稳定性的主要因素，热残余应力越小，尺寸稳定性越好，反之，尺寸稳定性越差。
In this paper, the dimension stability of SiCp/Al of composite is measured by hot and cold eyeling testing. The effect different factors on dimension stability is analyzed and the mechanism of dimension stability of composite is discussed. The research indicates that in the SiCp/M composite the more regular the reinforecement particle shope is and the larger particle size is and the slower cooling rate is, the better the dimension stability is. The sum of thermal residual stress is the primary factor of the composite dimension stability, the smaller the residual stress is, the better dimension stability is, on the contrary, the worse dimension stability is.
