摘　　要：随着科技的发展进步,镍基高温合金在航空航天、核电等高精尖领域得到广泛应用,其性能要求也不断提高。熔炼作为镍基高温合金制备过程中的一个关键环节,直接影响合金材料的整体品质和性能,选择适宜的熔炼工艺非常重要。目前常用的熔炼工艺包括真空感应熔炼(VIM)和真空自耗重熔(VAR)等,在实际应用中各有优势和不足之处,需进行合理选择、搭配,精确控制其参数,从而满足镍基高温合金越来越高的熔炼要求。本文对镍基高温合金的熔炼方法进行了详细的分析研究,以期为相关冶炼工作提供参考。With the development of science and technology,nickel-based superalloys have been widely used in high-precision fields such as aerospace and nuclear power,and their performance needs to be continuously improved.As a key link in the preparation process of nickel-based superalloy,melting directly affects the overall quality and properties of alloy materials,so it is very important to choose the appropriate melting process.At present,the commonly used melting processes include vacuum induction melting(VIM)and vacuum consumable remelting(VAR),etc.,which have their own advantages and disadvantages in practical applications,and need to be rationally selected and matched to accurately control the parameters,so as to meet the increasing melting demand of nickel-based superalloys.In this paper,the melting method of nickel-based superalloy is analyzed and studied in order to provide reference for related melting work.
