The effects of sintering temperature,holding time and hot pressure on the density and mechanical properties of a hot pressed(PM)powder metallurgy 30vol%TiC\-p/W composite have been investigated. An optimum process for the preparation of 30vol%TiC\-p/W composite with higher strength and toughness has been devised.The 30vol%TiC\-p/W composite has excellent high temperature strength.This is attributed to a brittle ductile transision of the tungsten matrix combined with the strengthening effect of hard TiC particles in the W matrix.
