Abstract In this paper, the 30 vol% SiCp/6061Al composites were prepared by vacuum hot pressing sintering. The effect of SiC particle size on the microstructure mechanical properties and wear behaviour of SiCp/6061Al composites was studied. From the results, it is shown that the SiC particle distribution increases firstly and then decreases with the increase of the particle sizes, the relative density, microhardness, elongation, and wear rate increase firstly and then slightly decrease. If the SiC particle size is 16 μm, the comprehensive properties of the composite are the best.

SiC粒径对SiCp/6061Al基复合材料微观结构和性能的影响

摘要 本文采用真空热压烧结法制备了30 vol% SiCp/6061Al复合材料。研究了SiC粒径对SiCp/6061Al复合材料微观结构力学性能和磨损行为的影响。结果表明,随着粒径的增大,SiC颗粒分布先增大后减小,相对密度、显微硬度、伸长率和磨损率先增大后略有减小。如果 SiC 粒径为 16 μm，则复合材料的综合性能最好。
