More Information
Summary:The present invention provides a process for preparing titanium nitride sintered masses having no residual pores and consisting of TiN solid solution particles and Ni solid solution matrix, in which a granulated powder of the following composition:TiN-pMo2C-qC-rNi-sMeCwherein: p is 5 to 20 wt %; q is 0 to 1.5 wt %; r is 15 to 30 wt %; s is 0 to 5 wt %; MeC is one or more carbides selected from VC, WC, TaC and NbC; with the proviso that q and s are not 0 wt % simultaneously; is compacted and sintered. The process according to the present invention can provide sintered TiN cermets of high density and a small grain size.
