“…One surface was WJP treated and marked as WJP, and the other was marked as untreated (UT). The parameter of a working pressure of 30 MPa and a standoff distance of 30 mm was used for the WJP enhancement, which was optimized in the early investigation (Ming et al , 2022). In the experiments, the WJP processing directions were longitudinal with a pitch of 1 mm.…”

“…Compared with SP and LSP, WJP is more suitable for application in nuclear power plants (Ming et al , 2022; Okimura et al , 2008). It can generate residual compressive stress without the formation of surface microcracks and inclusion, which plays an important role in the crack initiation stage.…”

“…It can generate residual compressive stress without the formation of surface microcracks and inclusion, which plays an important role in the crack initiation stage. Few investigations studied the WJP-induced microstructure change and the effect of change in microstructure and/or residual stress on SCC behavior (Ming et al , 2022; Okimura et al , 2008). Decease of SCC susceptibility was found, which was usually attributed to the optimization of stress state.…”

Purpose This paper aims to understand the effect of water jet cavitation peening (WJP) on stress corrosion cracking (SCC) behavior of alloy 600 and alloy 182 in high temperature water. Design/methodology/approach Surface and cross-section morphology, grain boundary microstructure, residual stress and strain distribution, hardness and surface roughness in water jet cavitation peened alloy 600 and alloy 182 were characterized. Findings A superior stress corrosion cracking resistance was obtained in 600MA, which can be attributed to the formation of the ultrafine grain layer and the higher magnitude residual compressive stress. Originality/value Relationship between WJP-induced microstructure and stress state change and SCC susceptibility was conducted. It could provide a theoretical basis for developing application of WJP in nuclear power plants.

“…However, due to the fixed champing mode and severe deformation, it is not suitable for machining components with complex shapes and low strength, as it may lead to serious structural changes [ 25 , 26 ]. The water jet peening process has the advantage of machining complex components with good mechanical properties [ 27 ]. However, it requires ultra-high pressure of 40 to 100 MPa, which imposes higher requirements for pressurizing devices.…”

Enhanced Strength–Ductility Synergy Properties in Selective Laser Melted 316L Stainless Steel by Strengthening Grinding Process

et al. 2022

Selective laser melted (SLM) 316L stainless steel (SS) has been widely employed in the fields of designing and manufacturing components with complex shapes and sizes. However, the low yield strength, low ultimate tensile stress, and low hardness of SLM 316L SS components hinder its further application. In this work, the strengthening grinding process (SGP) was used to enhance the mechanical properties of SLM 316L SS. The microhardness, residual stress, microstructure, and tensile properties of all the samples were analyzed. The results demonstrate that the SGP induced higher compressive residual stress and microhardness, as well as higher tensile properties. The maximum hardness and residual stress reached 354.5 HV and −446 MPa, respectively, indicating that the SGP resulted in a plastic deformation layer over 150 μm. The possible mechanisms have been discussed in further detail. Compared to the untreated sample, the SGP sample shows a significant improvement in yield strength (YS), ultimate tensile stress (UTS), and elongation (EL), increasing 30%, 25.5%, and 99.1%, respectively. This work demonstrates that SGP treatment could be an efficient approach to simultaneously improving the strength and ductility of the SLM 316L SS, which makes it more suitable for engineering applications.
