Abstract
Effects of addition of SiC to a WC-6%Co alloy on mechanical properties of the cemented alloy were investigated. The addition of SiC was made to the cemented alloy as a solid solution of WC-SiC. The cemented alloy containing less than 1% SiC showed good densification, and the transverse rupture strength of the alloy was increased considerably at the SiC content of 0.5% whereas the hardness of the alloy was decreased slightly. It is believed that the addition of SiC inhibited decarburization of WC which always occurs during the sintering process and contributed to the strengthening of the cemented alloy.
