Provided are a magnesium alloy plate excellent in a warm-plastic workability, its manufacturing method, and a worked member prepared by warm-plastic working the plate. The magnesium alloy plate is manufactured by applying a predetermined distortion to a rolled material (RS), which is not subjected to a heat treatment for recrystalization, and by not performing that heat treatment even after the distortion was applied. The distortion application is performed by heating the rolled material (RS) in a heating furnace (10), and by passing the heated rolled material (RS) between rollers (21) thereby to bend the rolled material (RS), so that the bent plate may have a half value width of the (0004) diffraction peak in the monochromatic X-ray diffraction, at 0.20 deg. to 0.59 deg. This alloy plate utilizes the residual distortion to cause a continuous recrystalization in the warm-plastic working operation thereby to manifest a high plastic deformability. |
