Abstract Cemented tungstencarbide yields plastically at room temperature in the presence of a large hydrostatic pressure component. By approximate analysis of the state of stress in supported opposed anvils and by measurement of the pressure at which the anvil tips exhibit a permanent deviation from planarity, we have obtained the yield stress of such materials. Finally, our value for the yield stress of a 3% cobalt cemented tungstencarbide is 86 kbar.
