Abstract

Deformed structures of cold rolled 70–30 brass have been studied using both textural and microstructural techniques to establish the twinning tendencies of different orientations. Extensive studies using transmission electron microscopy showed that there are significant volumes of material with near (110)〈112〉 brass (B) and (110)〈001〉 Goss (G) orientations formed at intermediate to high strains (65–85% reduction). Neither twins nor shear bands are found in these grains. Two highly significant results are that non-twinned B and G volumes are associated with deformation banding and that there is a considerable volume of material spread between (123)〈634〉 S and (135)〈712〉 B–S. A modified deformation pathway is proposed for brass texture formation which, by including deformation banding, predicts the existence of B, S, and B–S. The failure to include S and B–S orientations in low stacking fault energy texture description is due to the low resolution of 111 pole figures. © 1994 The Institute of Materials.
