Abstract

It is shown that a fatigue limit of the laboratory specimens and blades after ion-beam treatment and post-treatment vacuum annealing can be raised by 30-180% depending on the type of alloy and irradiation conditions. The results of the SEM surface investigations indicate on the connection of fatigue strength increase effect with both the change of the mechanism of crack origin and slowing down of the cracks propagation. Extra high fatigue limit values were detected for Ti-based alloy produced specimens and blades after power ion beam irradiation.
