采用先制预制块然后加压铸造的方法制得了致密均匀的ＳｉＣｐ／Ａｌ复合材料，与基体铝合金相比，其屈服强度提高４６％，抗拉强度提高２４％，弹性模量提高８７％． The compact and uniform SiCp / Al composites were obtained by prefabrication of prefabricated blocks and then compression casting. Compared with the matrix aluminum alloy, the yield strength was increased by 46%, the tensile strength by 24% and the elastic modulus by 87%.
