MAGNESIUM ALLOY USING RARE EARTH MAGNET SCRAPS AND MANUFACTURING METHOD OF THE SAME

摘要

PURPOSE: An magnesium alloy using rare earth magnet scraps and a manufacturing method thereof are provided to share substances between different industries through an open type circulation technology, thereby improving the efficiency of recycling rare earth resources. CONSTITUTION: An magnesium alloy using rare earth magnet scraps comprises; a step for inserting the rare earth magnet scraps into molten magnesium; a step for dissolving the rare earth magnet scraps in the molten magnesium; a step for liquid-permeating the molten magnesium inside the rare earth magnet scraps; and a step for dispersing rare earth elements included in the rare earth magnet scraps to the molten magnesium. [Reference numerals] (AA) Diffusion direction of Nd; (BB) Penetrating direction of liquid magnesium; (CC) Rare earth scraps; (DD) Nd-exhausted Fe-B composition; (EE) Nd diffusion in solid scraps; (FF) Nd oxide; (GG) Nd diffusion through liquid; (HH) Mg melt
