MAGNESIUM-BASED ALLOY FOR SEMI-SOLID CASTING HAVING ELEVATED TEMPERATURE PROPERTIES

摘要

A magnesium-based semi-solid alloy having improved creep resistance,ultimate tensile strength, tensile yield strength and average % elongation at150°C. Castings are cast from a semi-solid alloy slurry comprising, inweightpercent, between about 3 to 7% Aluminum, between about 0.5% and 3%Strontium with the balance being magnesium except for impurities commonlyfound in magnesium alloys. The semi-solid alloy slurry includes up to 5% orup to about 20% solid fraction by weight.
