Title:
MG-AL-CA-BASED MASTER ALLOY FOR MG ALLOYS, AND A PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2012/134243
Kind Code:
A2
Abstract:
The present invention relates to an Mg-Al-Ca-based master alloy for Mg alloys and to a production method therefor, and concerns an alloying master alloy used for magnesium or magnesium alloys. To this end, a feature of the invention is that, while the Ca:Al ratio in the composition is maintained at between 7:3 and 1:9, based on percentages by weight in the alloy, a balance of Mg is added in an amount of up to 85% of the entire weight of the master alloy, based on percentage by weight. The production method comprises the steps of: preparing the components of the master alloy by selecting a composition in which, while the Ca:Al ratio in the composition is maintained at between 7:3 and 1:9, based on percentages by weight in the alloy, there is a balance of Mg in an amount of up to 85% of the entire weight of the master alloy, based on percentage by weight; sequentially melting Mg, Al and Ca; completely melting the above constituents by applying an adequate amount of heat; and rapidly cooling the molten pool.
