Abstract

The effects of heat treatment upon some room-temperature properties of TiC-31 wt% cermet were mainly studied. The hardness, transverse-rupture strength, X-ray parameter, curie temperature and microstructure of the alloy held in vacuum at 700∼1300°C for 0.5∼25 hrs, or quenched from 700∼1300°C were observed. As the results, it was especially noticed that the TiC grains in this TiC-Ni system after a long time of heating have coalesced to form clusters, and such a change of microstructure would be detrimental to the mechanical properties at low-temperature.
