| Abstract | The gradient nanostructured (GNS) surface layer was prepared to enhance the high-temperature fatigue properties of reduced activation ferritic/martensitic (RAFM) steel. The GNS-RAFM steel showed high stability of microstructures at a high temperature of 550 degrees C/60 min due to the pinning effect of M23C6 and MX precipitates, which contributed to an improvement of fatigue life at 550 degrees C/260 MPa by 5.5 times compared to the original one. Moreover, the high-temperature fatigue resistance enhancement in the SMRT samples was supposed to be the synergistic contribution of compressive residual stress arising, grain nanocrystallization/refinement, and the strain delocalization introduced in the gradient nanostructure. |
