Conclusions
The increase in the fatigue strength resulting from SPD, apart from the effect of residual macrostresses and substantial hardening, is due in large measure to the fact that in the surface layer where fracture originates the local stresses decrease, the microdistortions become more uniform (with a martensitic structure), and the internal friction increases. All this increases the resistance to fatigue crack nucleation.
