Abstract

The disclosure relates to the technical field of preparing the metal material of magnesium alloy, and particularly provides a method for preparing biomedical magnesium alloy wires. The magnesium, zinc, and neodymium alloys are subject to smelting, casting, rolling, and other processes to prepare plates. The plates are subjected to a special mechanical stirring process to prepare a processing zone with the same thickness as the plates. After machining, the processing zone is used as the final product of the wire or drawn in multiple passes to finally form the wire with the required diameter. By introducing rolling and mechanical stirring processes, the disclosure improves the forming property of the wire, so that the alloy grains are significantly refined, the size of the second phase is greatly reduced and most of them are solid-soluble in the matrix, the strength of the obtained wire, and especially the elongation, is greatly improved, and better corrosion resistance is obtained, which meet the performance requirements of medical magnesium alloy wire.
