The variation of the energy release during the recrystallization process and the texture change were investigated by differential calorimetric analysis and X-ray texture measurements of Cu sheets cold rolled by various rolling procedures. Copper sheets of 2 mm thick were at first rolled in one direction (primary rolling), then rolled to a final thickness of 0.1 mm in the transverse direction (secondary rolling). The amount of deformation in the secondary rolling was 9 to 90% reductions in thickness. On slight secondary reductions less than 20%, the rolling texture changed little and the recrystallization texture showed a well-developed cube texture, whereas, the activation energy for the recrystallization decreased from 74 to 62 kcal/mol. For the specimens secondly rolled by 9% to 75%, the activation energy had an almost constant value of 62 kcal/mol. The condition for the “intrinsic” growth of the cube oriented grain would be easily collapsed, then only a slight reduction of secondary rolling affected the growth behavior of the cube grain. The predominance of the cube grain growth presumably originated from the configuration of the boundary regions between the cube component and the matrix in the deformed materials. However, no difference in the recrystallization behavior was found among the specimens by electron microscopy.
