Embodiment 1
[0052] The ultra-high-strength dissolvable magnesium alloy described in this embodiment is composed of the following elements in mass percentage: Sm8.0wt%, Sc 0.1wt%, Zn 1.0wt%, Ag 0.25wt%, Cu 1.0wt%, Ni 0.5wt% %, the mass percentage of impurity elements is 0%-0.1%, and the rest is Mg.
[0053] The preparation method of the ultra-high strength dissolvable magnesium alloy described in this embodiment is as follows:
[0054] 1. Weigh the raw materials according to the ratio of the above mass percentages. The above raw materials are pure magnesium ingots, pure zinc ingots, pure silver powder, pure copper, Mg-Sm master alloys, Mg-Sc master alloys, and Mg-Ni master alloys.
[0055] 2. Under the protection of argon, melt at 720°C, melt for 40 minutes, stir for 20 minutes, and refine for 30 minutes. After refining, heat up to 760°C, stand for 40 minutes, and cast at 660°C to form a semi-continuous ingot;
[0056] 3. Take the above ingot for homogenization treatment, at 480°C, hold f...
