Abstract: PURPOSE: A method of manufacturing MgB2 superconductivity which is doped with heterogeneity atom with using a mechanical alloying method are provided to manufacture a MgB2 wire in which critical current property is improved under a high magnetic field. CONSTITUTION: Material powder of MgB2 alloy and heterogeneity atom powder for doping are mixed to form compound powder(S2). A mechanical alloy method is performed for the compound powder(S3). A thermal process is performed for the compound powder enforcing the mechanical alloy method(S5). The compound powder which performs the mechanical alloy method is molded before enforcing a thermal processing step(S4). Mold through swaging or drawing to a wire after inserting the compound powder in the metallic conduit in a rod shape.
