Embodiment 1
[0171] The high-strength heat-resistant magnesium alloy in this example is composed of the following components by mass percentage: Gd: 8.5wt.%, Y: 2.5wt.%, Ag: 0.5wt.%, Sc: 0.01wt.%, Zr: 0.45wt.%. %, Zn: 0.2wt.%, the balance is Mg and unavoidable impurities.
[0172] The casting molding preparation of the high-strength heat-resistant magnesium alloy of this embodiment comprises the following steps:
[0173] (1) Magnesium alloy ingot preparation: mix pure Mg, pure Ag, pure Zn, Mg-Zr master alloy, Mg-Sc master alloy, Mg-RE (20~30wt.%) master alloy according to the above-mentioned rated mass percentage, Wash and dry, preheat.
[0174] (2) Put pure Mg, pure Ag, pure Zn, Mg-RE (20 ~ 30wt.%) into the crucible to melt and heat up to 740 ° C, then add Mg-Zr master alloy, Mg-Sc master alloy to stir and refining.
[0175] (3) Cool the melt down to 710° C. and stand still for about 40 minutes, and then perform casting.
[0176] (4) Solution treatment: heat-treat the casting at 520°C...
Embodiment 2
[0184] The difference between Example 2 and Example 1 is that the high-strength heat-resistant magnesium alloy consists of the following components by mass percentage: Gd: 9.5wt.%, Y: 3wt.%, Ag: 0.7wt.%, Sc: 0.04wt .%, Zr: 0.45wt.%, Zn: 0.2wt.%, the balance is Mg and unavoidable impurities. Solution treatment: heat-treat the casting at 510°C for 12h, then air-cool to room temperature. Aging treatment: heat-treat the casting at 225°C for 48 hours, then air-cool to room temperature.
