Title:
MAGNESIUM-BASED ALLOY AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2024/027053
Kind Code:
A1
Abstract:
A magnesium-based alloy, comprising (mass%): Al: 3-9%, La: 1.5-7%, RE excluding La: 0.2-0.3%, Zn: 0.01-0.8%, Ca: 1.5-4.0%, CaO: 0.01-0.2%, and the balance being magnesium and inevitable impurities. La, which does not generate a sharp phase, is selected as a main alloying element, and a small amount of other rare earth elements such as Y/Gd are added, such that the precipitation number of an Al-La phase is effectively increased, the size of the precipitated phase is reduced, and the dispersion degree thereof is improved. Accordingly, the strength performance is improved, and the plastic loss is reduced. In addition, a method for preparing the magnesium alloy is further provided.
