than those of the RD-LD planes, which are related to the different deformation mechanism. References [1] WANG Gang, ZHANG Kai-feng, WU De-zhong, WANG Jun-zhi, YU Yan-dong. Superplastic forming of bellows... of the bent tube experiences compression deformation mainly by tensile twinning, and the twinning makes the preferred orientation of wall materials change sharply. 2) The Vickers hardness......
