This study was conducted to investigate influence of Fine-Particle Bombarding (FPB) on the microstructure near the surface and fatigue properties of pure titanium. For comparison, a shot-peened material was used. The results showed that surface hardness and compressive residual stress of the FPBed material were higher than those of the shot-peened material. Furthermore, its microstructure near the surface was greatly fined through dynamic recrystallization and nano-crystallized. As a result, the fatigue strength of the FPBed material was improved more than that of the shot-peened material because propagation of intemal cracks to the surface was effectively suppressed by the formed layer.
