Welding of high entropy alloys: Progresses, challenges and perspectives

High entropy alloys (HEAs) and HEAs-related materials have developed rapidly over the last decade, and the key issues have gradually emerged when the welding of HEAs are required. Here, we provide a critical review on the state-of-the-art for the welding of HEAs-related materials, aiming to address the weldability of HEAs under the compositional diversity, different initial states, welding processes and parameters, joint configurations and...
