The solubility of WC in ZrC varied from 25 mol% at 1800°C to 65 mol% at 2550°C. There was no detectable solubility of ZrC in WC in the same temperature range. Tungsten carbide precipitates from supersaturated WC‐ZrC solutions as rods. The crystallographical relation between the precipitated phase and the matrix established by electron diffraction techniques is: [100] wc |[110] ZrC and [010] wc |[011] zrc . The interfacial planes were (001) for WC and (111) for ZrC. The hardness of the solid solution of 55 mol% WC and 45 mol% ZrC increased ∼ 10% after it was annealed at 1900°C.
