摘要
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。
The magnesium matrix composites SiCw/AZ91 with different SiC contents were prepared by powder metallurgy method, and the microstructure and mechanical properties of the composites were investigated. The results show that the SiCw distributes at the grain boundary diffusely after adding SiCw properly, and thus the strength and hardness of the composites are enhanced.
