Deformation and recrystallization textures in cross-rolled copper sheet

A study has been made of the deformation and recrystallization textures of 99.99% pure copper sheets which were cross rolled by 82 and 96% reduction in thickness and recrystallized in a salt bath at 450degreesC for 1h. The deformation texture was approximated by the {011}[755] orientation as the major component and {001}[100] as a minor component. These deformation texture components were it-ell simulated using the rate sensitive relaxed constraints model. The {001}[100] orientation was calculated to be metastable while the {011}[755] orientation was located in the middle of the rotation path between the stable orientations in two cross rolling directions. The recrystallization texture in the center layer of the 96% cross-rolled copper sheet was approximated by {86 50 9}[10 34 94] for each rolling direction. The evolution of the recrystallization texture was discussed based on the strain energy release maximization model.
