Abstract

Early stage of recrystallization behavior was investigated in high purity deformed iron with isolated crystal grains to elucidate the mechanism of recrystallization. Recrystallization of the isolated deformed grains was greater than that of the bi-crystal matrix. The recrystallized grains were observed in the RD×ND section at the tip portion of the deformed isolated grains extending in the rolling direction. Recrystallized grains were also observed inside the deformed isolated grains. The crystal orientations of the recrystallized nucleus were positioned where they were in the perimeter portion of the orientation spread of the deformed matrix, or there may have been the intermediate orientation between the matrix and the isolated grains.
