Archivio Istituzionale della RicercaIn this paper both theoretical background and experimental results are presented to investigate the effect of the surface finish on life of steel samples undergoing high cycle fatigue (HCF). Three groups of specimens with different surface finishing and a group of grinded specimens have been prepared and fatigue tested (Ra=0.8 μm). Surface temperature measurements of specimens during tests have been compared. Results have been discussed and analyzed basing on the main HCF damage models of steels.

Abstract
In this paper both theoretical background and experimental results are presented to investigate the effect of the surface finish on life of steel samples undergoing high cycle fatigue (HCF). Three groups of specimens with different surface finishing and a group of grinded specimens have been prepared and fatigue tested (Ra=0.8 μm). Surface temperature measurements of specimens during tests have been compared. Results have been discussed and analyzed basing on the main HCF damage models of steels.
