“…In the article by Bag et al, it was noted, among other things, that the development of cracks was slowed down in the zone affected by residual compressive stresses, and the distance between slowdowns for the samples after SP was equal to the austenite grain size [ 103 ]. A crack reduction was achieved for specimens between 3- and 5-grain size diameters, while the reduction of the stress amplitude from 1089 MPa to 931 MPa was twice as large as at a higher pressure.…”

“…Additively manufactured (AM) components made of ferrous and non-ferrous materials are systematically studied. AM processes for metals are typically divided into two groups; first is directed energy deposition (DED) processes like laser metal deposition LMD [ 38 , 143 ], the second is powder bed fusion (PBF) methods like selective laser melting (SLS) and direct laser metal sintering (DMLS) [ 101 , 102 , 103 ]. Thanks to them, it is possible to produce objects of an even more complex shape, but the material after printing requires additional processing to improve its properties.…”

Effects of Shot Peening and Cavitation Peening on Properties of Surface Layer of Metallic Materials—A Short Review

2022

Shot peening is a dynamically developing surface treatment used to improve the surface properties modified by tool, impact, microblasting, or shot action. This paper reviews the basic information regarding shot peening methods. The peening processes and effects of the shot peening and cavitation peening treatments on the surface layer properties of metallic components are analysed. Moreover, the effects of peening on the operational performance of metallic materials are summarized. Shot peening is generally applied to reduce the surface roughness, increase the hardness, and densify the surface layer microstructure, which leads to work hardening effects. In addition, the residual compressive stresses introduced into the material have a beneficial effect on the performance of the surface layer. Therefore, peening can be beneficial for metallic structures prone to fatigue, corrosion, and wear. Recently, cavitation peening has been increasingly developed. This review paper suggests that most research on cavitation peening omits the treatment of additively manufactured metallic materials. Furthermore, no published studies combine shot peening and cavitation peening in one hybrid process, which could synthesize the benefits of both peening processes. Moreover, there is a need to investigate the effects of peening, especially cavitation peening and hybrid peening, on the anti-wear and corrosion performance of additively manufactured metallic materials. Therefore, the literature gap leading to the scope of future work is also included.

“…Moreover, most of the available investigations on bending fatigue of shot peened aluminum alloys were also mainly attributed to Benedetti and coworkers [14][15][16]. The most recently reports by Lévesque et al [26] highlight that defects in the structure and shot peening induced surface roughness together degraded the fatigue resistance of the structure, which is of great significance because it has opened the prologue of the research on the surface integrity and damage tolerance of shot peened structures.…”

Characterization on the surface morphology, residual stress relaxation and fatigue life prediction of the changed intensity shot peening specimens machined from SS304 were carried out. The present work aims, first and foremost, to model the fatigue performance of shot peening specimens machined from SS304 in extra-low-, low-and high-cycle regime by clarifying the relaxation life component and fatigue life component with the total failure life, thereby successfully evaluating the fatigue performance of un-/0.1 mmA-/0.25 mmA-/0.4 mmA-peened components with satisfactory results in the whole cycle regime. It is, therefore, essential to provide a precise definition of the master life diagram on the purpose of evaluating the fatigue performance of shot peening components in service by linear interpolation of shot peening intensities considering the engineering applicability. Additionally, the characterization of multiple-fatigue crack initiation to failure was also identified by fractography analysis, which reasonably illustrated the non-conservative life prediction in the high-cycle regime.

“…In recent years, several research studies were focused on improving the mechanical properties of 300M steel through different surface treatment techniques. Bag et al [ 6 ] studied the effect of surface shot peening (SP) on the growth of short cracks in 300M steel. It was found that the compressive residual stress induced by SP treatment effectively hindered growths of short cracks along with a decreased crack growth rate and increased fatigue life.…”

Herein, gradient nanostructures (GNs) are created in 300M ultrahigh‐strength (UHS) steel by laser shock processing (LSP). Microstructure evolution and properties of GNs subjected to LSP with different pulse energies are thoroughly characterized on 3D profiler, scanning electron microscope (SEM), transmission electron microscope (TEM), X‐ray diffractometer (XRD), X‐ray stress analyzer, nanoindenter, and tensile tester. Results show successful creations of GNs in 300M steel after LSP treatments. With the increase in pulse energy, the size of the surface layer is refined from 15 nm (3 J) to 10 nm (7 J), and the corresponding grains are amorphized to some extent. Meanwhile, many substructure defects such as dislocation tangles and deformation twins (DTs) are noted in the subsurface. The dislocation density and the number of DTs increase with the pulse energy. Further, the high compressive residual stress is introduced to the 300M steel surface after LSP, and the corresponding hardness is improved substantially. The compressive residual stress, depth of the affected layer, and the hardness rise significantly with the pulse energy. Apart from improvements in strength and plasticity, the fracture morphology is changed from a typical ductile fracture to quasicleavage and ductile mixed fracture.
