Aluminium alloys are most suitable for light weight applications. This research paper investigates the fatigue strength of Aluminium alloy 2024-T3 after shot peeing process using nickel shots. Nickel shots are used in this research to investigate the influence of nickel on the fatigue strength of aluminum 2024-T3 alloy. Compressed air is used for shot peening process. Shot peening process parameter values are chosen based on response surface method (RSM) to conduct the experiments. Desirability approach is used to get the optimized values of process parameters. High cycle fatigue testing is performed to find the fatigue strength of specimens before and after shot peening process. An increase in the fatigue strength up to 34% is observed after peening using the nickel shots. FESEM and EDS tests revealed the presence of nickel on the surface of aluminium 2024-T3 specimen after shot penning with nickel shots.

“…After AWJP, the surface topography of target material becomes rough, which decreases the fatigue life of the target material. 6,7 Taking Ti6Al4V as the object, Anwar et al studied the profile of a single dimple after AWJP under different incidence angles by simulation. 8 Sequentially, Sara Bagherifard et al established a finite element simulation model to assess the surface roughness of the target material, and the study found that the shot velocity, shot diameter, and coverage ratio all had a significant influence on the surface roughness.…”

In this paper, the theoretical models of the surface topography and residual stress (RS) were proposed, and the abrasive water jet sequential peening (AWJSP) finite element models were established by using ABAQUS. Then, the formation mechanism of the surface topography in multiple passes AWJSP process and the coupling mechanism of RS in a single and multiple passes AWJSP process were analyzed. After that, the influence of the number of shots (i.e. N), the distance between the center of adjacent shots Dc, shot velocity v, and shot radius R on the surface topography and residual stress field (RSF) of the target were investigated. Results show that successive dimples were formed by single-pass AWJSP, the RSF formed by the impact of each shot will influence the previous RSF, and that will be coupled with it. In multiple passes AWJSP process, decreasing Dc can decrease the surface roughness, the surface smoothness of the target material will gradually become better, and the RSF will also be uniform. Under full coverage condition, the surface roughness Rt and mean width of the profile Rsm will gradually decrease with the decrease of Dc, while the change of Dc has little influence on the RSF. Increasing the v can increase Rt and Rsm, and it is beneficial to induce a large and deep compressive RS layer. Increasing the R can decrease Rt, Rsm remains unchanged, and it is beneficial to induce a deep compressive RS layer.
