Abstract:  
The rolling contact fatigue specimens of 40Cr steel were treated by shot peening after the compound heat treatment of ion-nitriding and induction hardening. In order to study the effect of shot peening on contact fatigue behavior of 40Cr steel after compound heat treatment, the contact fatigue test, fractography and metallography studies, hardness measurement as well as the residual stress analysis were conducted. Descriptors: Compound heat treatment (CHT); Shot peening after the compound heat treatment (CHT+SP); Ion-nitriding (IN); Induction hardening (IH); Carburizing hardening (CH); Shallow spalling; Deep spalling; Pitting; Surface crack
