摘　　要：我国高温合金的发展相比于国外,起步晚、进步快,但纯净度控制尚不能达到国际标准。本文综述了20世纪40年代到21世纪国际和国内镍基高温合金的发展,分类叙述了真空感应熔炼过程中较难去除的杂质元素对合金性能的影响及其含量控制方法,并对今后我国铸造高温合金提高合金纯净度进行展望。Compared with the overseas situation, the development of superalloy started relatively late but is fast at home. However, the purity can not reach the international standard. This paper made a brief summary of the development of superalloy at home and abroad from the 1940s to 21st century. It also described the influence of impurity on the performance of superalloy, the control method for impurity and the future prospect of the development of purifying melting technology.
