Abstract

The object of this study was to obtain information on the inhomogeneous structure of the WC-TiC solid-solution phase after sintering with cobalt or nickel acting as binder. For this purpose, the solubility of WC in TiC was determined at temperatures from 1500 to 2100° C. Furthermore, grain growth and phase decomposition behaviour were investigated in the temperature ranges 1450 to 1550° C and 1700 to 1850° C. Phase-decomposition of oversaturated mixed carbide solid solution which is not capable of further coarsening enabled the reaction constant at the solid-liquid interface to be determined.
