Abstract

The carbide structure of WC-17%TiC-40%ZrC-5%Ni cermet was mainly studied. It was found that the cermet showed an extremely fine carbide structure with high hardness and high strength when sintering cycle was specified. The structure was attributed to the phase separation of carbide solid-solution from one-phase to two-phases. Such a fine structure would similarly be obtained in other alloy systems.
