“…It can be observed that transverse direction shows higher surface stress values than longitudinal direction by 110-830% range which is consistent with the other researchers' findings [21][22][23]. It could be due to the bow wave generated in advance of rolling direction and relatively more material is pushed in transverse direction than longitudinal [24]. Also, this could be due to the atomic rearrangement in the rolling direction through sink-in and pile-up mechanism unlike in transverse direction [25].…”

“…This indicates that the impact of vibropeening with 8 h treatment time have reduced in intensity or energy, or that the imparted stress has possibly been relaxed after 8 h. On the other hand, in the longitudinal direction, the residual stress profile after 4 h treatment time is better than 8 h, with higher maximum compressive residual stress and a greater depth of influence. This proves that there could be stress relaxation with longer treatment time, which could negate the positive impact of vibropeening on the components [5]. This is essential to provide an understanding of the optimal process time for vibropeening.…”

“…However, this depends on the properties of each material, such as elastic modulus, hardness, and ductility, to name a few. Therefore, it is important to determine the saturation point of the treating material to avoid over-peening, when the residual stress profile will not have any improvement further or will even deteriorate [5].…”

Vibropeening is a surface treatment process, which combines the peening effect of introducing residual stress with the polishing effect of reducing surface roughness in one single process step. Vibropeening equipment induces vibrations into the media to impart residual compressive stresses in sub-surface layers, as well as polishing on the surface of the work piece. In addition to process parameters, such as vibration frequency, amplitude, and media mass, which are well known in literature, this paper will focus on the study of two additional parameters: immersion depth and process time. It was found that the lower-middle section of the vibratory trough produced the highest Almen deflection. Different continuous treatment times were also studied to explore the maximum introducible residual compressive stress state, and it was concluded that an optimal time range is required to achieve the best residual stress profile. The study demonstrates that different process parameters can influence the effectiveness of the vibropeening process, and that these can be potentially optimized for higher treatment capability.

“…Furthermore, studies on deep rolling coupled with heat treatment and/or elevated temperature [73][74][75][76], cryogenic treatment [39,77], aging [56], and certain surface treatments like shot peening [78,79], burnishing [80], and ultrasonic-induced hammering [81][82][83][84] were testified in the recent past. The major objective was to complement DR with the advantages of the latter.…”

The proposed review demonstrates the effect of the surface modification process, specifically, deep rolling, on the material surface/near-surface properties of commercial steels. The present research examines the various process parameters involved in deep rolling and their effects on the material properties of AISI 1040 steel. Key parameters such as the rolling force, feed rate, number of passes, and roller geometry are analyzed in detail, considering their influence on residual stress distribution, surface hardness, and microstructural alterations. Additionally, the impact of deep rolling on the fatigue life, wear resistance, and corrosion behavior of AISI 1040 steel is discussed. Engineering components manufactured by AISI 1040 steel can perform better and last longer when deep rolling treatments are optimized with an understanding of how process variables and material responses interact. This review provides critical insights for researchers and practitioners interested in harnessing deep rolling techniques to enhance the mechanical strength and durability of steel components across diverse industrial settings. In summary, the valuable insights provided by this review pave the way for continued advancements in deep rolling techniques, ultimately contributing to the development of more durable, reliable, and high-performance steel components in diverse industrial applications. The establishment of generalized standardizations for the deep rolling process proves unfeasible because of the multitude of controlling parameters and their intricate interactions. Thus, specific optimization studies tailored to the material of interest are imperative for process standardization. The published literature on the characterization of surface and subsurface properties of deep-rolled AISI 1040 steel, as well as process parameter optimization, remains limited. Additionally, numerical, analytical, and statistical studies and the role of ANN are limited compared with experimental work on the deep rolling process.
