Abstract Titanium alloys have been widely used as lightweight and high–strength structural materials in the aeronautical industry. Their forming and processing have always attracted much attention. It has been proven that the application of thermal hydrogen treatment technology to titanium alloys helps to improve their hot workability and optimize microstructural properties. In this paper, the research progress of superplastic forming/diffusion bonding technology of hydrogenated titanium alloy is reviewed. The influence of thermal hydrogen treatment on the microstructure, superplasticity and diffusion bonding of different kinds of titanium alloys is introduced. The influence mechanism is summarized. It provides a reference for industrial applications of superplastic forming/diffusion bonding technology of hydrogenated titanium alloy.
