The present invention relates to a TiC-based cermet body comprising TiC and WC so that the atomic ratio Ti/W is between 2 to 5, cobalt as the binder phase in an amount of between 5 to 25 vol%. Further, the cermet body comprises at least one element from group V of the periodic table, M x , so that atomic ratio Ti/M x is between 4 to 20 and the atomic ratio M x /W is between 1 to 6. The cermet body also comprises Cr in an amount such that the atomic Cr/Co ratio is from 0.025 to 0.14. The cermet body comprises both un-dissolved TiC cores with a rim of (Ti,W,M x )C alloy as well as (Ti,W,M x )C grains which have been formed during sintering. The present invention also relates to a method of making a cermet body. |
