The conclusion of an earlier study involving upsetting, the fact that the strain εst necessary for obtaining a given grain size at any temperature decreased exponentially with the absolute temperature of deformation, was verified also for rolling using a low alloy steel and electrical grade aluminium. It was found that, in order to achieve good correlation between the upsetting and rolling results, the rolls had to be preheated by 100 K and the heating temperature for rolling should be maintained at 50 K above the corresponding temperature for upsetting.
