Study on surface performance enhancement mechanism and control of 42CrMo steel by ultrasonic rolling composite processing
(English) 42CrMo steel is widely used in key load-bearing components subjected to low-speed, heavy-load, and cyclic service conditions, where fatigue failure is strongly governed by the surface residual stress state, microstructural stability, and surface integrity. URCP, combining static pressure and high-frequency vi...
