摘要	A 700 mu m-thick gradient nanostructured surface layer with enhanced hardness and compressive residual stress was produced on a rare earth addition bearing steel by surface mechanical rolling treatment under fine lubrication and cooling. Rotary bending fatigue tests showed that fatigue properties are significantly enhanced in the surface modified samples under the internal-induced failure mode, with the fatigue strength increasing from 1050 MPa in the as-received counterparts to 1200 MPa in them at a fatigue life of 107 cycles. Analyses revealed that the enhanced fatigue properties are related with the transfer of crack initiation site to a deeper region in the surface layer. And the formation of a thick gradient nanostructured surface layer with enhanced hardness and compressive residual stress contributes to the enhancement of fatigue properties of bearing steel.
