The purpose of the present study is to observe the coarsening behavior of WC grains in the WC-Co alloys with various Co contents under the constant carbon potential and thus to clarify the coarsening mechanism of faceted WC grains. Since the coarsening of WC grains is affected sensitively by carbon content in the WC-Co compacts, the carbon content in the liquid Co is controlled at a constant level in all experiments through the alloy compositions having slightly excess carbon content.
