Abstract The flow stress of eight alloy structural steels at high strain rate and high temperature has been studied using a cam plastometry compression machine capable of imparting certain given amount of deformation at a constant strain rate. The tests of the deformation temperature, strain rate and amount of deformation ranged between 850—1150℃, 5—80s~(-1) and 5—69% respectively. The effects of them on the flow stress of the steels were examined. The analysis by non-linear regression and comparison between the mathematical models of flow stress with two types of temperature term were conducted. Thus, a mathematical model of flow stress with great confidence of the eight alloy structural steels is proposed, and its regression coefficient is also recommended.
