摘要
本文对粉未冶金法制备的ＳｉＣ和ＴｉＣ颗粒增强铝基复合材料进行了研究。试验表明，在颗粒含量相同、尺寸相当的条件下，ＴｉＣ增强Ａｌ基复合材料的强度和模量均低于ＳｉＣ增强Ａｌ基复合材料，但其屈强比却明显高于ＳｉＣ增强Ａｌ基复合材料。高温长时间等温处理对ＴｉＣ颗粒增强纯Ａｌ复合材料的强度没有明显的影响。
he SiC and TiC particulates reinforced alumin um matrix composites fabricated by powder metallurgy technique were investigated. It is indicated that on the condition of same particulate content and approxi-mate particulate size,the strength and modulus of the TiC particulate rein forced Al matrix composite are lower than those of the SiC particulate rein forced Al matrix composite,but yield strength/tensile strength ratio of the former is obviously higher than that of the latter. The isothermal heat treatment at elevated temperature for long time has no obvious effect on the strength of TiC particulate reinforced pure Al com-pOsite。
