Fatigue property and fracture analysis on cold-expanded hole structure of GH4169 alloy
Cold expansion (CE) was applied on the centre-hole plate of GH4169 alloy. The fatigue lives, as received and after CE, were investigated at 825 MPa/600 ℃/<i>R</i>=0.1. Surface roughness before and after CE, residual stress profiles during fatigue cycles were studied. And the influence of...
