Preparation method of single-phase supersaturated solid solution magnesium-zinc alloy

The invention relates to a preparation method of a single-phase supersaturated solid solution magnesium-zinc alloy. The preparation method belongs to the technical field of metal materials, and comprises the steps of after melting magnesium and zinc, stirring, refining, and casting into an alloy ingot; carrying out homogenization heat treatment and severe plastic deformation on the alloy ingot; and finally carrying out solution treatment on the magnesium-zinc alloy subjected to severe plastic deformation, taking out for quickly cooling in air or water, and obtaining a microscopic structure of a single-phase supersaturated solid solution. A lot of grain defects are good for the diffusion of the zinc in a matrix, and during a heat treatment process, the dissolution rate of a second phase is greatly accelerated, so that the grains are further refined, and the mechanical property and the processing performance of the material are improved. 种单相过饱和固溶体镁锌合金的制备方法，属于金属材料技术领域，通过将镁和锌熔化后，经过搅拌、精炼处理，浇铸成合金铸锭，将合金铸锭进行均匀化热处理和剧烈
