Fatigue &Fracture of Engineering Materials &Structures, Volume 47, Issue 11, Page 4000-4011, November 2024.Abstract In this study, multifunction cavitation (MFC) was performed on low‐alloy steel (AISI 4140 steel) rods with different hardnesses to increase their fatigue limit. It was found that a high compressive residual stress was generated on the surface of steel rods by MFC and that the magnitude of the compressive residual stress tended to increase with
