Abstract
Ti(CN) ceramics with 0-2 mol%WC were prepared by sintering in a flowing nit rogen environment at 1973 and 2073 K for 3.6 ks. Part of the WC particles w ere dissolved in the liquid, and triggered a faster sintering. As the WC co ntent increased, the grain size initially increased, and then decreased due to increasing number of WC particles surviving dissolution. The flexural s trength was inversely related to the grain size. The hardness of Ti(CN)-2 m ol%WC sample was increased by a post-sintering heat treatment in an argon e nvironment.
