Abstract
The texture evolution in AA1050 sheet metals during deep drawing process was experimentally investigated. The measured textures varied with the initial crystal orientations and strain path. In the specimen parallel to RD, the grains oriented at the D component rotated toward the Cu component and the grains having orientations along the fibre rotated toward the G {110}<001> and P{110}<111> during deep drawing. In the specimen parallel to 45° with respect to RD, the initial crystal orientations between the G and RG also rotated toward the G and P during deep drawing. In the specimen parallel to TD, the initial crystal orientations between the B{110}<112> and RG {110}<110> rotated toward the P{110}<111> during sleep drawing. The deviation from the plane strain state in the flange area gave rise to a decrease in the orientation density around P.
