摘要
A study was conducted to demonstrate the use of an equal channel angular rolling (ECAR) process to produce AZ31 magnesium alloy sheets with a changed texture and improved ductility. The study was carried out to investigate the press formability for AZ31 magnesium alloy sheet produced by ECAR at room temperature and was compared with that of the normally rolled sheet. The as-received sheets of AZ31 magnesium alloy of 800×120×1.9 mm were prepared by unidirectional hot rolling for the investigations. The sheets were heated at 623K for 3min, and then rolled in the ECAR device with an ECAR mould having an oblique angle of 115°, an oblique an oblique radim (r) of 2mm and a channel height (H) of 1.8mm. The strain during ECAR was simulated by means of a rigid-plastic finite element method (FEM) code DEFORM-2D. The FEM simulation showed the deformation at the comer of mold channel during one pass of ECAR.
