Variation of Plastic Strain Ratios of α‐Brass Sheet WithTensile Strain

A study has been made of the changes in the instantaneous plastic strain ratios alongvarious directions of α-brass sheet as a function of tensile strain. The α-brass sheet wasfabricated by 88% cold rolling and subsequent annealing at 450℃ for 1.5 h, which lead tocomplete recrystallization. The recrystallization texture of the α-brass sheet could beapproximated by {110}〈 110 〉 . The plastic strain ratio along the rolling direction decreasedwith increasing tensile strain, whereas those along 45 90 to the rolling direction werealmost independent of tensile strain. The results were in agreement with those calculatedusing the recrystallization textures based on the Taylor-Bishop-Hill full constraintsmodel.
