Abstract: AbstractFormation of solid solution (Ti, W) (C, N) in ultrafine grain TiCN base cermets has been studied. The solid solution realised high hardness of cermets. The formation of the W-rich solid solution had been found to be affected by sintering conditions, such as sintering temperature, N2 gas pressure and the ratio N/(C + N) of starting powder. The sintering conditions were considered to introduce some denitrification, which accelerates precipitation and growth of the W-rich solid solution phase around TiCN core structures. Further effect of ...
