Description In the present study, ultra low carbon steel samples were deformed in near plane-strain mode with different strains, strain rates and temperatures. Estimates of in-grain misorientation developments were obtained respectively for the gamma-fiber (ND//< 111 >) and alpha-fiber (RD//< 110 >) oriented deformed grains. Though a general drop in in-grain misorientation was observed with increase in deformation temperature, the highest reduction of 70% showed a clear increase at the intermediate deformation temperatures. Under these condition(s), the misorientation increase in deformed gamma-fiber grains was more substantial than in alpha-fiber grains. The phenomenon was related to the preferred appearance of grain interior strain localizations. The study brings out a clear possibility of optimizing the stored energy advantage in the deformed gamma-fiber through controlled warm working.
