چکیده انگلیسی
It is vital to control fatigue life in different industrial sectors, and to improve this, surface treatments are usually used. Some of the most important surface treatments are Shot Peening (SP), Laser Shock Peening (LSP) or Deep Rolling (DR), which are used to improve the surface properties and resistance to cyclic loading of the components. The idea of this article is to focus on Deep Rolling and revise the state of its development at the present time, with a particular emphasis on implementation and changes in materials. A comparison of Deep Rolling versus other surface has been made, and different processes that can improve the effects of Deep Rolling, such as heat treatments, are shown. It can be concluded that the pressure of the tool during the process is the most important control parameter for Deep Rolling and that the residual stresses and strain hardening have the greatest influence in terms of fatigue life. Moreover, selecting the correct values of the other control parameters for DR, depending on the material on which DR is to be done, allows increased compressive residual stresses, a hardened layer near the surface and lower surface roughness, all of which produce an improvement in fatigue life.
