Surface characteristics and fatigue behavior of shot peened Inconel 718

[Display omitted] •Shot peening has a detrimental effect on fatigue life in low cycle fatigue.•Shot peening can increase fatigue life from two to twenty times in HCF.•The presence of significant residual stresses is the controlling factor in HCF.•Shot peening induced residual stresses mainly redistr...
