Abstract Hot deformation characteristic of superaustenitic stainless steel 254SMO has been studied by isothermal compression testing in the temperature range of 950-1,200 ℃ and strain rate range of 0.01-10 s^-1. The activation energy of 496 kJ/mol was calculated by a hyperbolic-sine type equation ov...
