The logarithmic relationship between flow stress and strain rate is expressed by a single straight line with the slope of 0.15 at a constant temperature in all strain rate range examined, unlike in cemented carbides showing the sigmoidal behaviour. The solid solution hardening due to the addition of Cr3C2 and VC is negligible in the Co-9WC-lCr3C2-0.5VC alloy and the mutual relation in flow stress is different between the cemented carbides and their binder phases in region I. The plastic flow in region I in WC-Co cemented carbides cannot be explained by the flow stress or flow behaviour in the binder phase.
