采用粉末冶金法制备了不同配比的Si Cw/AZ91镁基复合材料,并研究了其显微组织和力学性能。结果表明,加入适量的SiCw后,SiCw弥散分布在晶界上,有效提高了镁基复合材料的强度和硬度。
Different proportions of Si Cw / AZ91 magnesium matrix composites were prepared by powder metallurgy and their microstructures and mechanical properties were studied. The results show that SiCw disperses in the grain boundary after adding appropriate amount of SiCw, which effectively improves the strength and hardness of magnesium matrix composites.
