SiC_p/ZL101A composites were prepared by hot-pressed sintering process (HPS) with the raw material of ZL101A powders obtained by gas atomization and SiC particles. The content of SiC particles was 10%(Volume fraction, the same below)、20%、30% and 40%. Microstructure was investigated by metallographic microscope, scanning electron microscopy and transmission electron microscopy. The effect of different content of SiC particles on microstructure, mechanical properties and friction behavior were studied using s...
