“…However, the σ m introduced by shot peening had no obvious change with the increase of diameter under the same pellet material. Wu et al [25] numerically simulated the effect of shot peening on 2024 aluminum alloy and obtained the results consistent with this paper, and they proposed that the residual stress distribution was affected by the pellet diameter, shot peening velocity, and incident angle.…”

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.

“…Formation of the compressive residual stress through UNSM treatment can be explained as follows: the peening of the surface the material was from cyclic plastic loading, due to progressive peening effects. Outer layers experience an in-plane stretching plastic deformation, whereas the elastic sub-surface attempts to maintain its original shape, hence generating compressive residual stress at the surface [39,40]. Additionally, a small portion of the applied stress is stored in the form of residual stresses within the structure as a tangled network of dislocations [41].…”

To suppress stress corrosion-cracking, compressive residual stresses, such as shot peening, laser peening, water jet peening, ultrasonic peening, and ultrasonic nanocrystal surface modification (UNSM) are utilized. However, among the numerous techniques, there is little research about the corrosion effect of detailed conditions, such as static load or amplitude in UNSM. A study on UNSM among various techniques of adding compressive residual stress to Alloy 600 was conducted. The focus of this study was on the effect of the static load in UNSM on the corrosion properties of Alloy 600. Microstructure analysis was conducted using an optical microscope (OM), a scanning electron microscope (SEM), and electron backscattering diffraction (EBSD), while compressive residual stress was measured using a nano-indentation technique. A cyclic polarization test and the AC (Alternating Current)-impedance measurement were both used to analyze the corrosion properties. An increase in static load under critical static load enhanced the grain boundary diffusion, consequently strengthened the passive film, and facilitated the surface diffusion, thereby improving the passivation of Alloy 600. However, higher static loads over the critical value can lead to an increase in the friction between the striking tip and the surface, thereby creating an overlapped wave, which reduces the corrosion properties.

“…5–8 In addition, an undesired byproduct of SiCp/Al composites during cutting process is the generation of residual stress at machined surface and subsurface, which is most likely to influence the integrity of newly finished surface as well as related fatigue performance. 9 Therefore, a detailed evaluation of surface integrity following machining process is indispensable for designing cutting strategies and preventing premature failure of machined structures during fatigue services.…”

High-efficient machining of SiC particles reinforced composites is always challenging mainly due to their poor surface integrity. In this study, a two-phase finite element model including the Al alloy matrix with Johnson-Cook model and SiC particle with elastic-brittle failure model were developed. The main purpose is to comprehensively investigate particle removal mechanisms and surface integrity following simulation and experimental studies on milling SiCp/Al composites. Specifically, the distributions of residual stress along the depth direction were predicted using finite element model. Results indicated that compressive residual stress mainly appeared on the machined surface, while tensile residual stress distributed at deeper depth down to 0.02 mm. Besides, different relative positions between tool and particle induced specific particle removal modes, which eventually led to various surface defects. Higher level of cutting speed (180 m/min) and feed rate (0.09 mm/tooth) aggravated surface defects and increased the thickness of broken-SiC layer in subsurface. The simulated machined surface defects and surface residual stress correlated well with the experimental observation, and the maximum error value of cutting force was less than 15%. The proposed finite element model was efficient to predict cutting force and distribution of residual stress along the depth direction.
