Abstract
The magnesium alloy sheet disclosed herein has dispersed therein particles of an intermetallic compound containing an additive element (e.g., Al) and Mg (a typical example of which is MgAl), and the ratio obtained by dividing the diffraction intensity of the main diffraction plane (4,1,1) of the intermetallic compound by the diffraction intensity of the c plane (0,0,2) of the Mg alloy phase in an XRD analysis of the surface of the sheet is 0.040 or more. The method includes: a casting step of producing a cast material composed of a magnesium alloy containing an additive element by continuous casting; a heat treatment step of holding the cast material at 400° C. or higher and then cooling the cast material at a cooling rate of 30° C/min or less to produce a heat-treated material; and a rolling step of subjecting the heat-treated material to warm rolling to produce a rolled sheet.
