Abstract
The deformation behavior of TiC-Mo2C-Ni cermet affected by the additional TiN was mainly studied at 873-1273 K by means of three-point bend tests. It was found that the high temperature deformation of the cermet was highly suppressed by the addition of TiN with increasing test temperature, and that the creep rupture strength of the TiN-contained cermet became superior to that of usual WC-base alloys, in particular, at 1273 K and under low stresses. These results obtained in the TiN-contained cermet were considered to be due to the restraint of the dynamic recovery of binder phase during deformation.
