Notes:
A new technique has been developed, which enables one to randomize the basal planetexture formed in wrought magnesium alloys, AZ31B. Rolls with about 60 mm in diameter havingwavy surface of 8 mm in wave length and 3 mm in peak to valley depth were used. The peak lineswere perpendicular to the roll axis. The alloy sheet specimen of 50 x 50 mm with 2.5 mm inthickness was heated at temperatures ranging from 623 to 723 K, and then immediately wavy-rollformed. The specimen was re-heated at the same temperature, and then wavy-roll formed withrotating at 90 degree. Such a process was repeated at eight times, then finally flat-rolled with aslight reduction. Electron backscattered diffraction analyses showed that the basal plane texturewas predominantly formed in the start material, while after the cross wavy roll-forming,accumulation of basal plane tended to be diffusely distributed
