A recycling process of Mg alloy chips to obtain superconducting MgB2 is proposed. In the present process, mechanical milling was used to mix and grind AZ31 chips and boron powder. Fine AZ31/boron powder mixture can be fabricated via a mechanical milling process. Mechanical milling can reduce the process time to synthesize MgB2 powder. An AZ31/boron mixture via mechanical milling can be reacted completely to MgB2 by heating at 700 oC for 3 h. Sintered MgB2 bodies produced by a pulsed electric current sintering technique showed approximately 30 K as the superconducting critical temperature.
