MAGNESIUM-BASED ALLOY PRODUCED USING A SILICON COMPOUND AND A CALCIUM COMPOUND AND METHOD FOR PRODUCING SAME

WIPO Patent Application WO/2012/161485

A2

The present invention relates to a magnesium-based alloy produced by adding a silicon compound and a calcium compound directly to molten magnesium or a molten magnesium alloy. The present invention also relates to a method for producing the magnesium-based alloy. More particularly, the silicon compound and the calcium compound are injected into the molten magnesium or molten magnesium alloy so as to induce a reduction reaction between said molten materials and said two compounds (the silicon compound and the calcium compound). The present invention also relates to a magnesium alloy and to a method for producing same, in which the silicon and the calcium produced by said reduction reaction are converted to an intermetallic compound in said molten materials simultaneously with said reduction reaction. The method for producing a magnesium-based alloy comprises the steps of: melting magnesium or a magnesium alloy into a liquid state; adding a silicon compound and a calcium compound to said molten magnesium or said molten magnesium alloy; removing oxygen from said silicon compound and said calcium compound through a reduction reaction between said molten materials and said compounds; and combining the silicon and calcium produced by said reduction reaction in said molten materials.
