摘要

In this work, the GH4169 superalloy specimens were shot-peened at two different intensities (0.15 mmA and 0.3 mmA) to improve the fatigue properties, and the fatigue behavior of the shot-peen-treated specimens was investigated in the high cycle fatigue (HCF) and very high cycle fatigue (VHCF) regime. The results of the HCF and VHCF tests indicated that shot peening improved the fatigue properties of the material. In addition, it has shown that the tensile residual stresses introduced by excessive shot peening intensity reduce the benefits of shot peening in terms of improving fatigue properties.
