Abstract

A study has been made of the changes in the instantaneous plastic strain ratios along various directions of α-brass sheet as a function of tensile strain. The α-brass sheet was fabricated by 88% cold rolling and subsequent annealing at 450℃ for 1.5 h, which lead to complete recrystallization. The recrystallization texture of the α-brass sheet could be approximated by {110} 〈110〉. The plastic strain ratio along the rolling direction decreased with increasing tensile strain, whereas those along 45 90 to the rolling direction were almost independent of tensile strain. The results were in agreement with those calculated using the recrystallization textures based on the Taylor-Bishop-Hill full constraints model.
