Title:
AGING TREATED MAGNESIUM ALLOY MATERIAL AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2019/172047
Kind Code:
A1
Abstract:
This aging treated magnesium alloy material contains from 0.3% by mass to 1% by mass (inclusive), preferably from 0.3% by mass to 0.7% by mass (inclusive), more preferably from 0.3% by mass to 0.55% by mass (inclusive) of Ca, and one or more alloy elements selected from at least among 0.5% by mass or more but less than 3.5% by mass of Zn and 0.1% by mass or more but less than 3% by mass of Al, with the balance being made up of Mg and unavoidable impurities. This aging treated magnesium alloy material has bake hardenability; the magnesium alloy has a 0.2% proof stress of 150 MPa or more; and precipitates that are composed of Mg, Ca and Al are dispersed on the (0001) plane of the magnesium matrix.
