TL;DR: In this article, shot peening and dual peening were performed on laser hardened 17-4PH steel in order to improve the fatigue life after laser hardening treatment, and the results showed that initial residual stresses had no influence on the finial residual stress distribution.

TL;DR: In this article, cyclic properties and behavioral trends developed using smooth, axial specimens of steels simulating the various microstructures found in surface processed componentry are used to predict cyclic stability.
Abstract: Procedures are presented for analyzing the cyclic stability and influence on fatigue resistance of residual stress patterns arising from mechanical and thermal surface processing treatments such as shot peening and induction hardening. Cyclic properties and behavioral trends developed using smooth, axial specimens of steels simulating the various microstructures found in surface processed componentry are used to develop criteria to predict cyclic stability. the rate of relaxation for prescribed straining levels, the failure initiation point (surface or subsurface), and expected fatigue lifetime. The validity of the approach is verified using experimental data from the literature. Finally, the incorporation of these procedures in modern computer-based fatigue analysis routines, and opportunities for further enhancements, are discussed.

TL;DR: Cavitation shotless peening (CSP) method, where impacts are generated by a submerged cavitating jet (without shots), was used to introduce compressive residual stress in titanium alloy, Ti-6Al-4V for the purpose of enhancing the conventional fatigue and fretting fatigue life and strength.
Abstract: Cavitation shotless peening (CSP) method, where impacts are generated by a submerged cavitating jet (without shots), was used to introduce compressive residual stress in titanium alloy, Ti-6Al-4V for the purpose of enhancing the conventional fatigue and fretting fatigue life and strength. This method provided higher compressive stress at surface as well as up to a depth of 40 μm from the surface than that with the shot peening method. Further, the surface treated by CSP was considerably less rough compared to that by the shot peening method, which is a highly desirable feature to improve the fretting fatigue performance.

TL;DR: In this article, four series of Al 6063 alloy specimens, as-received, conventionally shot peened, severely shot-peened and severely shotpeened, followed by a slight mechanical grinding are subjected to block wear tests with lubrication, according to ASTM G77 standard.
Abstract: Recent developments in shot peening demonstrate that it can be applied using unconventional parameters in order to obtain nanocrystals on a thin surface layer of the treated material. These microstructural modifications have shown to be able to induce superior fatigue and corrosion properties, but still few data are available about their effect on wear behaviour of the materials. In this study, four series of Al 6063 alloy specimens, as-received, conventionally shot peened, severely shot peened and severely shot peened followed by a slight mechanical grinding are subjected to block on ring wear tests with lubrication, according to ASTM G77 standard. The results evidence the significant role played by the applied shot peening treatments on wear behaviour of the 6063 aluminium alloy with respect to the as-received not peened material. The important effect of the surface roughness is also highlighted. The data are discussed on the basis of roughness, surface layer microstructure, microhardness trends and the wear marks observed by means of scanning electron microscopy.

TL;DR: An experimental study of high-pressure waterjet peening on 7075-T6 aluminum alloy was conducted to investigate the effects of waterjet on high-cycle fatigue life and fatigue crack growth.
Abstract: An experimental study of high-pressure waterjet peening on 7075-T6 aluminum alloy was conducted to investigate the effects of waterjet on high-cycle fatigue life and fatigue crack growth. Unnotched hourglass-shaped circular cross section test specimens were fatigue tested in completely reversed rotating bending (R =S min /S max = -1) to determine fatigue life behavior (S-N curves). Single-edge-notched flat tensile test specimens were tested in the tension-tension fatigue crack growth tests (R=S min /S max =0.1) to determine fatigue crack propagation behavior (da/dN versus AK). Surface characteristics and fracture surfaces were evaluated by scanning electron microscopy (SEM). Results show that waterjet peening can increase high-cycle fatigue life, delay fatigue crack initiation, and decrease the rate of fatigue crack propagation.
