The article explores the in-depth residual stress evolution of a surface-rolled titanium alloy subjected to fretting fatigue. The study aims to provide data for establishing an accurate fretting fatigue life prediction model by examining the surface residual stress distribution at different stages of fretting fatigue loading. The research highlights the complex stress distribution at the fretting wear zone and the impact of fretting wear on the evolution of residual stress, emphasizing the role of contact stress and fatigue stress in this process. The study suggests practical engineering approaches to mitigate residual stress release during fretting fatigue loading, such as using lubricants and employing techniques like induction hardening for surface strengthening.
