摘要
本文以Ａｌ、Ｃｕ、Ｍｇ等纯金属粉料及普通工业磨料用ＳｉＣ颗粒为原料，借助于液相烧结及热挤压工艺，制备了１０％ＳｉＣｐ（５μｍ）／Ａｌ和２０％ＳｉＣｐ（２０μｍ）／Ａｌ复合材料，并对其性能、基体成分的均匀性及ＳｉＣ颗粒与基体界面的结合状况进行了测试分析。研究结果表明，按此工艺制备的１０％ＳｉＣｐ（５μｍ）／Ａｌ复合材料具有很高的力学性能，由于该工艺简单易行，无需特殊设备，故具有低成本的优点。本文试验还表明，过度强化热挤压工艺有时会导致ＳｉＣ颗粒的碎裂，从而造成材料性能的下降。
y means of liquid sintering and hot extrusion,composites 10%SiCp(5μm)/Al and 20% SiCp( 20μm)/Al were prepared from commercial Al,Cu,Mg powder and SiC particles, The material proper-ties, homogeneity of matrix composition and the interface between metal matrix and SiC particulates wereexamined The test results show that the mechanical proporties of 10%SiCp(5μm)/Al prepared by thismethed are high and the cost is relatively iow because of simplified processing. The investigation also showsthat over-strengthened hot extrusion may lead the particles cracking and therefore to cause the materialproperties.
