    摘要： A magnesium alloy material having excellent impact resistance is provided. The magnesium alloy material is composed of a magnesium alloy that contains more than 7.5% by mass of Al and has a Charpy impact value of 30 J/cm 2 or more. Typically, the magnesium alloy material has an elongation of 10% or more at a tension speed of 10 m/s in a high-speed tensile test. The magnesium alloy is composed of a precipitate, typically made of an intermetallic compound containing at least one of Al and Mg, and contains particles having an average particle size of 0.05 µm or more and 1 µm or less dispersed therein. The total area of the particles accounts for 1 % by area or more and 20% by area or less. The magnesium alloy material containing fine precipitate particles dispersed therein has high impact absorption capacity through dispersion strengthening and has excellent impact resistance.
