“…Finally, the residual stresses after shot peening presented S-shaped distribution along the thickness direction. The similar trend was observed in shot peening simulation of steel, in work by Dieng et al [ 21 ], Zhou et al [ 27 ], and Wu et al [ 29 ]. The literature indicated that the surface compressive stresses were introduced by the elastic deformation, whereas the internal compressive stresses were introduced by the plastic deformation, and their magnitudes were mainly related to the material being shot peened [ 23 ].…”

Welding is one of the essential stages in the manufacturing process of mechanical structures. Friction stir welding structure of aluminum alloy has been used as a primary supporting member in aerospace equipment. However, friction stir welding inevitably generates residual stress that promotes the initiation and propagation of cracks, threatening the performance of the welded structure. Shot peening can effectively change the distribution of residual stress and improve the fatigue properties of materials. In this paper, friction stir welding and shot peening are performed on 2219 aluminum alloy plates. The residual stress fields induced by friction stir welding and shot peening are measured by using the X-ray diffraction method and incremental center hole drilling method, and the distribution characteristics of residual stress fields are analyzed. The effect of the pellet diameters and pellet materials used in shot peening on the redistribution of welding residual stress field are investigated. The pellet diameter used in the experiment is in the range of 0.6–1.2 mm, and the pellet material includes glass, steel, and corundum. This study provides guidance for the application of shot peening in friction stir welding structure of 2219 aluminum alloy.

“…Although many scholars have studied a lot of shot peening [ 29 , 30 , 31 ], the experimental research on shot peening of aluminum alloy-welded structures is rarely involved. In addition, operators mainly depend on experience to select shot peening parameters in the manufacturing practice [ 32 ].…”

Type 316 stainless steel is a material that is often used in the medical world, especially as a material for making bone implant plates. However, the use of stainless steel as an implant material, stainless steel must be treated to increase the hardness and adjust the level of roughness on the surface. In this study, shot peening was carried out on the 316 stainless steel surface. The shooting parameters used were 2, 4, 6 minutes for the shooting duration, and 0o, 15o, 30o, 45o for the shooting angle, as well as the diameter of the steel shot used, i.e. 0.6 mm and 1 mm. The results of this study indicated that there was a change in the characteristic properties of 316 stainless steel, namely the hardness and surface roughness.

“…Kim et al applied shot peening to aluminum alloys and verified that compressive residual stress improved the fatigue life [7]. In addition, the surface and mechanical characteristics have been improved using shot peening in many studies [8,9]. However, shot peening has low precision because it is impossible to adjust the positions of the injected metal balls accurately.…”

Ultrasonic nanocrystal surface modification (UNSM) technology was applied to the surfaces of specimens additively manufactured by powder bed fusion (PBF). The changes in roughness and hardness due to the UNSM were set as objective functions, and the optimal conditions for the main parameters were derived through the response surface method (RSM) and Box–Behnken design (BBD). Regression analysis-based mathematical models for predicting the surface hardness and roughness are presented and validated. The RSM results show that the surface roughness is highly dependent on the load and ball tip diameter, and the surface roughness significantly improves as the inter-pass interval and ball tip diameter decrease. Through BBD and ANOVA, the optimal conditions for the improvement of surface characteristics were found to be a load of 40 N, inter-pass interval of 10 μm, and ball tip diameter of 2.38 m. The surface treated under these optimal conditions exhibited a hardness of 497 Hv and surface roughness of 1.32 μm, which were significantly improved compared to the values for an untreated specimen. In addition, it was confirmed that the grains are significantly refined after UNSM, and scratch resistance increases for the top layer of the surface directly affected by the UNSM horn.
