Title:
MAGNESIUM ALLOY MATERIAL
Document Type and Number:
WIPO Patent Application WO/2011/071024
Kind Code:
A1
Abstract:
Disclosed is a magnesium alloy material having excellent impact resistance. The magnesium alloy material comprises a magnesium alloy containing more than 7.5 mass% of Al and has a Charpy impact value of 30 J/cm2 or more. Typically, the magnesium alloy material has an elongation of 10% or more in a high-speed tensile test at a tensile speed of 10 m/sec. The magnesium alloy has, dispersed therein, precipitates, typically particles each of which comprises an intermetallic compound containing at least one of Al and Mg and which have an average particle diameter of 0.05 to 1 μm inclusive. The total surface area of the particles is 1 to 20% by area inclusive. The magnesium alloy material has such a structure that fine precipitate particles are dispersed therein, and therefore has high impact absorption performance and excellent impact resistance due to dipersion strengthening.
