To obtain an intrinsic stress-strain response with no effects on stress due to the friction between the sample and the anvils or on the temperature increase due to adiabatic heating, a method of compensating for a stress-strain response was proposed. Using the stress-strain response that was compensated for, a processing map, consisting of both power dissipation efficiency and flow instability map, was constructed. On the basis of our observations using EBSD, it was found that the processing map after the compensation can be effectively used to well predict the optimum hot forging conditions.
