摘要

The thermal-mechanical properties of WHT1300HF high strength steel were tested by isothermal uniaxial tensile method at various strain rates (0.05, 0.2, 0.5 and 1 s~(-1)) and temperatures (700, 750, 800 and 850 °C) and analyzed by constitutive equations. The results show that increasing deformation temperature leads to significant reduction in the level of flow stress and work hardening exponent of the steel; however, increasing strain rate results in noticeable increase in the stress level and work hardening. Arrhenius-type constitutive equations were used to describe the flow behavior of the steel at elevated temperatures. With the constants of n, a, lnA and Q determined by the approximation method, the relative error between the calculated and tested flow stresses is smaller than 5.15 %, suggesting a high level of confidence in the developed constitutive equations.
