Abstract
An Mg-base alloy shows that an Mg-base alloy, which is added Zn and Al to magnesium, has a composition represented by (100-a-b) wt % Mg-a wt % Al-b wt % Zn, and satisfying 0.5≦b/a. The alloy can reduce yield anisotropy, which is a serious problem for the wrought magnesium alloy, while maintaining a high strength property. The alloy is produced by additive elements, such as Zn and Al, which are easily obtained in place of rare earth elements.
Claims8
An Mg-base alloy containing Zn and Al added to magnesium, comprising a composition represented by (100-a-b) wt % Mg-a wt % Al-b wt % Zn and satisfying 0.5≦b/a;
- wherein quasi-crystal phase particles or their approximate crystal phase particles are dispersed in the magnesium matrix, the content of the quasi-crystal phase or the approximate crystal phase is from 1% to 40%, and the range of the particle size is from 50 nm to 5 μm.
