The invention relates to a preparation method of a super-plastic toughness tungsten alloy material. The alloy material comprises the following raw materials of, in percentage by mass, 30%-55% of nickel Ni, 12%-25% of aluminum Al, and the balance tungsten W, so that a single-phase solid solution tungsten alloy is formed, and the method comprises steps of multi-element alloying design, high-energy ball milling, suspension smelting and reverse temperature field forging. According to the tungsten alloy material, the plastic toughness is good, the high plasticity, high compactness, high impact toughness and fine grain homogenization requirements of some special functional components on the tungsten alloy material are met, the elongation rate of the tungsten alloy material prepared by compared with the traditional process is improved by about 1 time, and the impact absorption energy is improved by more than 1 time. 一种超塑韧性钨合金材料的制备方法，原料为镍Ni质量分数为30%～55%、铝Al质量分数为12%～25%、余量为钨W，使其形成单相固溶体钨合金，包括多元合金化设计、高能球磨、悬浮熔炼、反向温度场锻造。本发
