Abstract The effect of thickness of specimen on the recrystallization texture of cold-rolledcopper strips under different percentage of reduction and with or without the surfacelayer has been investigated.The recrystallization texture of specimens of 0.84—0.02mmin thickness corresponding to a reduction of 88.7—99.7%,was found to have a nearlyperfect cubic texture.No concentrated cubic texture was observed in the specimens of0.01mm in thickness under a reduction of 99.8%.However,for specimens with cubi-cally aligned grains,cold-rolled to 0.01 mm in thickness(under a reduction of 98.6%),a rather concentrated cubic texture was developed after annealing at 900℃.The effect of strip thickness on the recrystallization texture has been found to bedifferent for different percentage of reduction.Under a smaller reduction of 88.7%,the specimens,less than 0.04mm in thickness,did not give a concentrated cubic texture.Whereas,for specimens under larger reduction(96—99.7%),no significant effect of stripthickness on the development of recrystallization texture was observed.The decreasing in thickness of specimens suppresses the occurrence of second re-crystallization but no pronounced effect on the grain orientation of the second recrystal-lization texture has been noticed.
