Apparent energy of activation for hot working of vanadium microalloyed steel
Abstract
Two-stage linear In [sinh(ασca)] vs.1/T plots, based on isothermal continuous and anisothermal multipass torsion curves, indicate the double Q HW behaviour of a V-steel. Above T nr , Q HW is independent of all variables but strain. Below T nr (which is interpass time dependent), i.e., in a temperature range in which interpass recrystallization is supressed, Q HW is not only increased but that based on multipass curves is also interpass time dependent, and only valid for multipass working operations.
