Abstract (en)
[origin: EP2351863A1] A formed product of a magnesium alloy having excellent impact resistance and a magnesium alloy sheet suitable as a material for the formed product are provided. The formed product is produced by press-forming a magnesium alloy sheet having an Al content of 7% by mass to 12% by mass and has a flat portion that is not subjected to drawing deformation. In a metal texture in a cross section of the flat portion in the thickness direction, the number of coarse intermetallic compound (Mg 17 Al 12 ) particles having a particle size of 5 µm or more present in a surface area region extending from a surface of the flat portion to a position one-third of the thickness from the surface in the thickness direction is five or less. The formed product has a texture in which the number of coarse precipitations d 1 is small and in which fine precipitations d 0 are dispersed. The formed product is less likely to be dented even when impacted because of dispersion strengthening owing to the fine precipitations and solid-solution strengthening owing to Al that sufficiently forms a solid solution.
