摘　　要：固溶强化镍基高温合金服役温度高,抗高温氧化和抗腐蚀能力好,被广泛用于制造航空发动机以及超临界发电站等高温零部件。相比于沉淀强化镍基高温合金,固溶强化镍基高温合金焊接性相对较好,通过调整焊接工艺和合金成分即可避免焊接裂纹的形成。随着固溶强化镍基高温合金应用范围的不断扩大,高温合金与异种材料的焊接展现出巨大的研究价值。因此,综述了固溶强化镍基高温合金及其与异种材料焊接技术的研究进展,主要涉及氩弧焊、激光焊接、电子束焊接以及钎焊、扩散焊和摩擦焊接方法,并对固溶强化镍基高温合金焊接研究进行了展望。Solid solution strengthened nickel-based superalloy has high service temperature,good high temperature oxidation resistance and corrosion resistance,and is widely used in the manufacture of high temperature parts such as aero-engine and ultra-supercritical power station.Compared with precipitation strengthened nickel-based superalloy,the weldability of solid solution strengthened nickel base superalloy is relatively better,and the formation of welding cracks can be avoided by adjusting welding process and alloy composition.With the increasing application of solid solution strengthened nickel-based superalloys,the welding of superalloys and dissimilar materials shows great research value.Therefore,the research progress of solid solution strengthened nickel-based superalloy and its welding technology with dissimilar materials is reviewed in this paper,which mainly involves argon arc welding,laser welding,electron beam welding,brazing and diffusion bonding,and the research prospect of solid solution strengthened nickel-based superalloy welding is also discussed.
