Abstract
The high temperature bend-deformation characteristics of TiC-Mo2C-(TiN)-Ni cermets were studied at 873-1273K in relation to the carbon content. It was found that the plastic deformation of the cermets began to take place at about 873K, and it was suppressed with higher carbon content in the temperature range up to about 1073K; but at the higher temperature the effect of carbon content was reversed. The TiN contained cermet showed a smaller plastic deformation than the conventional cermets independently of test temperatures and carbon contents. The effect of carbon content in the cermets was attributed to the variation in the carbide grain size which is a function of carbon contents.
