摘要: Multi-component high-entropy alloys (HEAs) have intrigued intensive attentions in the metallic materials fields due to their unprecedented properties including excellent radiation resistance, exceptional strength-ductility synergy at cryogenic temperature and good high-temperature stability. As such, HEAs are promising candidates for many engineering applications in extreme environment. To promote the fabrication and application of HEAs, exploiting HEAs-brazing technique is indispensable due to its cost-effectiveness, simplicity and excellent adaptability to sample configuration. Besides, owing to high-entropy and sluggish diffusion effects, HEAs also can be used as brazing filler metals in the brazing technology. The short review first discusses the brazing of HEAs with different fillers, and the interfacial microstructures and joining properties are summarized. Subsequently, the brazing of traditional ceramics to themselves or to metals with novel HEA filler metals is introduced. Besides, the summary and expectation of the coming research topics are also listed in the conclusions.
