Abstract: Heterogeneous joining components of ultra-high temperature composites and superalloys can not only give full play to the extreme high-temperature resistance and lightweight advantages of ultra-high temperature composites but also take into account the excellent processability and mechanical properties of superalloys. They have broad application demands in key equipment fields such as aero-engines and aerospace engines. However, due to significant differences in physical and chemical properties between ultra-high temperature composites and superalloys, achieving high-performance and high-reliability brazed joints between them has long been a research focus of scholars in China and abroad. In this paper, the main brazing methods for ultra-high temperature composites and superalloys were reviewed, and the key challenges in their brazing were elaborated. In view of these challenges, the research progress on brazing of ultra-high temperature composites, including C_f/C, C_f/SiC, SiC_f/SiC, and ZrB₂-SiC-C, with superalloys was elaborated with emphasis on two aspects of brazing filler metal selection and design, as well as joint residual stress prediction and regulation. On this basis, the development directions of heterogeneous brazing between ultra-high temperature composites and superalloys were prospected.
