Abstract
Magnesium alloys having improved high-temperature properties, especially improved resistance to creep, contain from 1.25 to 3.0% silver, 0.5 to 2.5% of rare metals including at least 60% neodymium and from 2.5 to 7.0% thorium. Optimum properties are obtained by high-temperature solution treatment followed by aging at a lower temperature.
