Abstract

This study investigates the effect of heating mode on the sintering of Copper-SiC metal matrix composites containing up to 7.5 wt.% SiC. The sinterability of the Cu-SiC system consolidated in a 2.45 GHz multimode microwave furnace has been critically compared with that processed in a radiatively heated (conventional) furnace. As compared to conventional sintering, microwave processing has resulted in a greater densification. It was observed that an increase in SiC content resulted in a higher hardness of the materials for both the heating modes. For all compositions, the electrical conductivity and hardness of microwave-sintered Cu-SiC composites are higher than those of their conventionally sintered counterparts.
