PRODUCTION METHOD FOR MAGNESIUM ALLOY USING GRAIN REFINER, AND MAGNESIUM ALLOY PRODUCED IN ACCORDANCE THEREWITH

摘要

The present invention relates to a production method for magnesium alloy using a grain refiner, and to a magnesium alloy produced in accordance therewith. More specifically, the present invention relates to a production method for magnesium alloy comprising: a step (step 1) of producing an aluminium master alloy by adding a carbonate based powder to an aluminium melt; and a step (step 2) of producing a magnesium alloy by adding the aluminium master alloy produced in step 1 to a magnesium melt; and relates to a production method for magnesium alloy comprising: a step (step 1) of producing an aluminium master alloy by mixing a carbonate based powder and aluminium (Al) metal chips and adding the mixture to an aluminium melt; and a step (step 2) of producing a magnesium alloy by adding the aluminium master alloy produced in step 1 to a magnesium melt; and also relates to a magnesium alloy produced in accordance therewith.
