Abstract
To expect sintering effect by the prevention against denitrification similar to that obtained in the sintering of TiNX-Ni mixed powder compacts1), sintering characteristics of TiN-Ni-Ti ternary mixed powder compacts were studied in connection with phase relationship. The maximum sintered density in the sintering condition at 1500°C for 1 hr in vacuum, was obtained at the composition ratio of the binder, Ni/Ti = 3/2, since a shrinkage was prevented from the liberated nitrogen gas in the Ni rich composition and a small amount of liquid phase in the Ti rich composition. Sintering of the TiN-18 wt% Ni-12 wt%Ti mixed powder compact was promoted by the liquid phase equilibrated with three phases, i.e., TiNX TiNi3 and TiNi at 1150°C, where the rate of densification during liquid phase sintering was controlled by phase boundary reaction.
