Study on the SiC-Al Co-continuous Phase Composites

摘要：

　　SiC/Al co-continuous phase composites were fabricated by pressureless infiltration technology with reticulated silicon carbide porous ceramics as matrix and aluminum or magnesium as reinforcement phase.The effect of magnesium addition and holding time on the relative density,mechanical properties and macro morphology of the composites was investigated.The results showed that the porosity of SiC/Al co-continuous phase composites decreased with the increase of the holding time.The wettability of SiC and Al was improved with the addition of Mg.The hardness of SiC/Al co-continuous phase composites increased with the increase of the holding time.SiC and Al combined closely at longer holding time.
