Patent ID: 7156931

Claim:
A method for producing a magnesium-based alloy comprising the steps of: a. loading alloying components into a crucible in the form of a master alloy including i. Al—remainder ii. Zn—2.5–3.5 wt. % iii. Si—24.0–28.0 wt. % iv. Mn—6.0–9.0 wt. % b. pouring molten Mg into the crucible to form an alloy i. heating ii. aging; and iii. stirring said alloy c. introducing a Ti-containing fusion cake with a fluxing agent to said alloy i. continuously agitating the cake in said alloy to form a magnesium based alloy d. cooling the magnesium-based alloy e. loading Ca under the Mg f. soaking; and g. casting said magnesium-based alloy.
