ABSTRACT:
A magnesium-based alloy is proposed which can be used for manufacturing various parts by casting. The alloy is highly heat-resistant and has good mechanical properties both at room temperature and at temperatures up to 300.degree. C. The parts manufactured from the proposed alloy can operate even at 400.degree. C for a short period of time. The alloy contains from 0.8 to 6 wt.% yttrium, from 0.5 to 4 wt.% neodymium, from 0.1 to 2.2 wt.% zinc, from 0.31 to 1.1 wt.% zirconium, up to 0.05 wt.% copper, and up to 0.2 wt.% manganese, the rest being magnesium, on condition that no less than 50% of the total amount of yttrium and neodymium additions enters the solid solution after thermal treatment.
