Ti( C, N) based cermets were prepared by hot isostatic pressing ( HIP) after vacuum sintering in this article. The influences of the different HIP temperature and time on the mechanical properties and microstructure of the cermets were investigated. Results show that HIP can effectively eliminate the internal hole and refine the crystal gain. It is found the reasonable HIP treatment temperature and time is 1 550 ℃ for 30 min, and the transverse rupture strength( TRS) , hardness and density of this material are improved to about 22. 9%, 1% and 1. 2%, respectively.
