To provide a magnesium alloy sheet excellent in warm plastic formability, a production method thereof, and a formed body produced by performing the warm plastic forming on this sheet.
The magnesium alloy sheet is produced by giving a prescribed strain to a rolled sheet RS that is not subjected to a heat treatment aiming at recrystallization and by not subjecting the rolled steel sheet RS to the heat treatment after the giving of the strain. The strain is given in such a way that: the rolled sheet RS is heated in a heating furnace 10; the heated rolled sheet RS is passed between heated rollers 21 to give bending to the rolled sheet RS; and the strain-given sheet has a half peak width of 0.2 deg or more and 0.59 deg or less in a (0004) diffraction peak in a monochromatic X-ray diffraction. The alloy sheet forms continuous recrystallization during warm plastic forming through the use of the remaining strain, thereby exhibiting high plastic deformability.
