利用金相法和XRD定量分析法对SiC颗粒增强铝基复合材料的SiC颗粒体积分数进行测定。用定量金相法测得SiC增强铝基复合材料SiC颗粒的体积分数为58.6%,用XRD定量分析法测得的体积分数为62.7%。
The SiC particle volume fraction of SiC particle reinforced aluminum matrix composites was determined by metallographic method and XRD quantitative analysis. The volume fraction of SiC reinforced aluminum matrix composite SiC particles measured by quantitative metallography was 58.6%, and the volume fraction measured by XRD quantitative analysis was 62.7%.
