The TiC0.7N0.3- and TiCo.5No.5-Mo2C-WC-Ni cermets were sintered in vacuum or nitrogen (PN2< 2.7 kPa), and the structural changes were examined in relation to the amount of additional WC(up to 30 vol% in total amount of Ti(C,N) plus WC) and sintering conditions. It was found that an additional WC remained in the structure and the amount increased as the nitrogen content in the cermet and PN2 increased. This is because WC tends to be checked to dissolve in the surrounding structure (Ti(C,N)-Mo2C solid-solution) under the conditions as above. Such a non-equilibrium structure having a remaining WC phase is considered to be important for further development of nitrogen contained cermets.
