Influence of Geometric Parameters on Residual Stress in Hollow Cylindrical Parts Subjected to Induction Surface Hardening
There is clear evidence that residual compressive stress (RCS) at the surface of mechanical component can significantly improve the fatigue strength of components subjected to cyclic load [1-3]. In many cases shot peening is considered as a process leading to the desired stress distribution [1-3]. At the same time, a number of investigations shows a possibility to obtain a high RCS at the surface of treated component for processes such as induction hardening [4-5]. However, induction hardening does not necessarily guarantee high level of RCS, moreover there is evidence that residual tensile stress might be developed in some cases [6].
