Abstract
A heat-resistant and soluble magnesium alloy, and a preparation method having an elemental composition at the following atomic percentage: Lu 0.10% to 8.00%, Ce 0.001 to 0.05%, Al 0.10% to 0.60%, Ca 0.001% to 0.50%, Cu 0.01% to 1.00%, Ni 0.01% to 1.00%, impurity elements <0.30%, and the rest is Mg, and formed in magnesium alloys are high temperature phase of Lu5Mg24, Mg2Cu, Mg2Ni, Mg12Ce, Al11Ce3 and (Mg, Al)2Ca, and Long Period Stacking Ordered (LPSO) phases as Mg—Lu—Al and Mg—Ce—Al. The magnesium alloy has good mechanical performances at 150° C., and a dissolution rate of 30 to 100 mg·cm−2h−1 in a 3% KCl solution at 93° C.
