ABSTRACT In order to study the thermally activated characteristics of plastic deformation and the effect of alloying element on the thermal activation of structural steels, the properties of plastic deformation for 20g and 13Ni3CrMoV steels have been examined in the temperature of 77—473K and strain rate of 〓.
