中文摘要

镍基高温合金因其高温下具有优异的强度、抗氧化性及耐腐蚀等性能，广泛应用于工业燃气轮机、航空发动机燃烧室等关键部件的制造。熔化焊接方法是一种连接和修复这些关键零部件的有效方法，然而液化裂纹是熔化焊过程中面临的重要问题，限制了镍基高温合金的应用。本文综述了近年来镍基高温合金熔化焊液化裂纹的研究进展，介绍了液化裂纹形成过程中液膜的形成机理和开裂准则，归纳了通过调整合金成分、改善母材焊前组织状态、优化焊接工艺参数、采用辅助外场、改善冷却条件等方法抑制液化裂纹的策略。未来的研究需要进一步厘清多组元对液化裂纹的协同影响机制，建立更加完善的液化裂纹开裂准则。

Abstract

Abstract

Nickel-based superalloys are extensively used in the crucial hot-section components of industrial gas turbines, aeronautics, and astronautics because of their excellent mechanical properties and corrosion resistance at high temperatures. Fusion welding serves as an effective means for joining and repairing these alloys; however, fusion welding-induced liquation cracking has been a challenging issue. This paper comprehensively reviewed recent liquation cracking, discussing the formation mechanisms, cracking criteria, and remedies. In recent investigations, regulating material composition, changing the preweld heat treatment of the base metal, optimizing the welding process parameters, and applying auxiliary control methods are effective strategies for mitigating cracks. To promote the application of nickel-based superalloys, further research on the combination impact of multiple elements on cracking prevention and specific quantitative criteria for liquation cracking is necessary.
