A recycling process of Mg alloy chips to obtain superconducting MgB 2 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 °C for 3 h. Sintered MgB2 bodies produced by a pulsed electric current sintering technique showed approximately 30 K as the superconducting critical temperature.
