【Abstract】 The returned materials of nickel-based cast superalloys contain a variety of rare and precious metal elements, which has important recycling and reusing value. In this paper, the current recycling status of the reverts of nickel-based cast superalloys at home and abroad and the mainstream purification technology of the returned materials were reviewed. On this basis, the effective reuse technology and development trend of the returned materials in the future were prospected, which provided reference for the recycling of the returned materials in related industries in China.更多还原
