The invention discloses a method for improving the rotating bending fatigue strength of a high-strength TC21 alloy, and belongs to the technical field of multi-gradient structures of the high-strength TC21 alloy. Firstly, ultrahigh-frequency electromagnetic induction heating is adopted to enable TC21 alloy to form a lamellar structure, a lamellar structure and a double-state structure and a structure gradient layer with gradual transition of the double-state structure from the surface to a core part; and then the TC21 alloy surface layer is subjected to ultrasonic rolling, and a nanometer gradient structure is formed on the surface. And finally, a multi-gradient tissue structure consisting of a nano-gradient lamellar tissue, a micron lamellar tissue, a lamellar and dual-state tissue and a core dual-state tissue is formed. After the TC21 alloy is subjected to ultrasonic rolling treatment, the surface roughness is reduced, and residual compressive stress is introduced, so that the crack initiation resistance of the material is improved; and a lamellar and dual-state structure transition region from the subsurface to the core part can prolong a crack propagation path and prolong the spinning fatigue life.
