“…When the gear's surface became completely covered with pits, it showed highly uneven. Research by Neslusan M et al [48] analyzed the Barkhausen noise emitted by AISI304 austenitic stainless steel during shot peening, revealing that excessive shot peening can lead to surface wrinkling and microcracks on the sample. Coverage dwindled the surface roughness of LSM gears by 47.6%, 33.4%, and 14.8%, respectively.…”

In this paper, shot peening (SP) was employed as a post-processing technique for the laser surface melted (LSMed) gear. The aim was to improve the contact fatigue performance of laser surface melting+shot peened (LSMSPed) gears. The microstructure, surface roughness, residual stress, microhardness of C40 steel gears before and after SP treatment were characterized using scanning electron microscopy, X-ray diffraction stress analyzer, contour measuring instrument, and hardness tester. Fatigue test of gear was carried out with a Forschungsstelle für Zahnräder und Getriebebau (FZG) testing machine. Following the laser surface melting (LSM) treatment, a molten layer was observed on the gear teeth surface. The experimental results indicated that SP induced a hardened layer with a certain thickness and plastic deformation on the surface of LSMed gears. Importantly, as the SP parameters increased, there's a corresponding reduction in both the average grain diameter and the maximum grain diameter. The reduction was most pronounced when the shot diameter reached its maximum value. It's worth noting that once the optimal threshold for SP parameters is surpassed, the residual compressive stress and microhardness on the LSMSPed gear surface do not exhibit a continuous growth trend. Furthermore, the rise in SP parameters resulted in a gradual increase in the surface roughness of LSMSPed gears, albeit to varying degrees. In light of the combined effects of grain refinement, residual compressive stress, microhardness, and surface roughness, the contact fatigue performance of LSMSPed gears improved with increasing SP parameters. Notably, when comparing the contact fatigue life of LSMed gears with that of LSMSPed gears, we observed a substantial enhancement. However, it's essential to highlight that when the shot diameter reaches its maximum value, the contact fatigue life of the LSMSPed gear, somewhat unexpectedly, decreased.

“…According to Figure 4, grain refinement, strain-induced martensite transformation and an increase in residual strain (dislocation density) were introduced. Neslušan et al (2022) also calculated the fraction of strain-induced martensite in the surface layer (Figure 5). It can be found that the fraction of martensite in the surface layer was increased with the increase of SP cycles and decreased along the depth direction.…”

Purpose This paper aims to review the effect of traditional shot peening (SP), laser shock peening (LSP) and water jet cavitation peening (WJP) on microstructure evolution and corrosion behavior of austenitic stainless steels 316L and 304. Design/methodology/approach The effect of SP, LSP and WJP on corrosion behavior of 316L and 304 were discussed in terms of surface peening–induced change in surface roughness, stress state and grain size. Findings Residual compressive stress and grain refinement were introduced after SP, LSP and WJP treatment in 316L and 304 stainless steels. Superior corrosion resistance can be obtained by WJP compared with SP and LSP. Originality/value The relationship between SP-, LSP- and WJP-induced change in microstructure and stress state and corrosion resistance was summarized.

“…During the shot peening process, the substrate surface produced plastic deformation that cannot be retracted, causing a warpage of the surface. Some studies have shown that the residual stress induces martensitic phase transformation [8][9][10][11] and the steels become sensitive to LME [14]. Martensite shows body-centered tetragonal (bct) structure, whereas austenite shows face-centered cubic (fcc) structure.…”

Lead-bismuth fast reactor is considered to be the most promising solution to meet the enormous energy demand in the future. The 15-15Ti austenitic stainless steel with outstanding corrosion and irradiation resistance has been proposed as main cladding candidate material for lead-bismuth fast reactor. However, the mechanical properties of 15-15Ti are weakly influenced by LBE. Shot peening as one of surface strengthening technique can efficiently improve metal mechanical properties. In this paper, shot peening (SP) treatment was applied on 15-15Ti. The microstructures and compositions were investigated using Optical Microscope, Scanning Electron Microscope and X-Ray Diffraction. It concludes that the material hardness is improved, and the residual stress induced by SP did not cause martensitic phase transformation on the sample surface. The presence of slip bands and other obstacles in the reinforcement layer improved the yielding and tensibility of the material.
