本发明公开了一种过饱和固溶体锌铜合金的制备方法及其在制备血管支架中的应用，属于金属材料技术和生物医用材料领域，本发明通过将锌和铜经过局部性质计算后得出准确的质量分数，按一定质量分数比例熔化后搅拌或高能超声，浇铸成合金铸锭，将合金铸锭进行大塑性变形，最后对经过剧烈塑性变形处理后的锌铜合金进行固溶处理，随后取出在介质中进行快速淬火冷却，即可得到单相过饱和固溶体的显微组织，最终经过拉拔制成的毛细管，晶粒细小，第二相明显减少。

The invention discloses a preparation method of a supersaturated solid solution zinc-copper alloy and its application in the preparation of vascular stents. It belongs to the field of metal material technology and biomedical materials. The invention obtains accurate results by calculating the local properties of zinc and copper. After melting according to a certain mass fraction ratio, stir or high-energy ultrasound, cast into alloy ingots, the alloy ingots are subjected to large plastic deformation, and finally the zinc-copper alloy after severe plastic deformation is solution treated, and then taken out Quick quenching and cooling in the medium can obtain the microstructure of single-phase supersaturated solid solution, and finally the capillary tube made by drawing has fine grains and the second phase is obviously reduced.
