“…According to these authors, the higher the deep rolling force, the higher the reduction in surface roughness. A roughness reduction was also observed by Martins et al [9] after deep rolling hardened AISI 4140 steel (40 HRC), with the Rq value of the deep rolled samples being approximately 4.5% of that of the turned samples. However, Rodríguez et al [10] noticed an increase in the Rz value when excessive force is applied in deep rolling of AISI 1045 steel.…”

“…As previously mentioned, deep rolling can increase the surface hardness and induce compressive residual stresses [2], in addition to reduce the surface roughness [6], features responsible for the enhancement of the fatigue strength. An increase in the fatigue strength of various alloys after deep rolling was reported by a number of authors: Ti-6Al-4V titanium alloy [6], AISI 304 and 316 austenitic stainless steels [2], AISI 1045 medium carbon steel [7], Al7075 aluminum alloy [12] and AISI 4140 low alloy steel [9]. Prabhu et al [5] reported that the deep rolling force was the most relevant parameter on the fatigue life of AISI 4140 low alloy steel.…”

Deep rolling is an effective and economically viable mechanical surface treatment that induces surface deformation by the action of a rolling tool. It is capable of reducing roughness, increasing hardness and inducing compressive residual stresses on the workpiece surface, thus increasing the fatigue strength of the component. This behavior, however, is only achieved with use of suitable parameters. This work investigates the surface topography and fatigue life of hardened AISI 4140 steel subjected to turning followed by deep rolling under distinct conditions. The ndings indicates that for the turned samples, roughness increases with turning feed rate, resulting in fatigue life reduction. Deep rolling promotes a roughness reduction and an increase in fatigue life and, surprisingly, the samples with the highest surface roughness after turning achieved the longest fatigue lives after deep rolling. The areal power spectral density (APSD) analysis of the surface topography was able to identify distinct effects of deep rolling for each level of pressure used. The morphology analysis indicates an initial loss of orientation, followed by the creation of a new orientation after deep rolling under high pressures. Furthermore, the interaction between deep rolling feed and deep rolling pressure presents a signi cant effect on the roughness parameters, indicating that different behaviors depend on each parameter level used. Deep rolling also affects the form of the fatigue fracture, reducing the number of nucleation sites, and modifying the nal overload fracture site.

“…A. M. Martins et al [48,49] extensively investigated the effect of DR on the fatigue life of AISI 4140 steel material along with considering the influence of machining parameters. Although it was acknowledged that DR enhanced the fatigue life of turned samples in most instances, in specific cases, DR was not fully effective in eliminating the detrimental effects, particularly in the samples turned with higher feed rates.…”

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.

“…These five Research has shown that the maximum profile peak height (R p ), the maximum profile valley depth (R v ) and the total height of the profile (R t ) reflect the height and depth of the profile, while the arithmetic mean deviation (R a ) and the root mean square deviation of the profile (R q ) reflect the dispersion degree of variations in the profile. These five evaluation indicators can effectively characterize the micro-texture of coarse aggregate surfaces [36][37][38][39]. Hence, the five indicators, including the two indicators calculated by Equations ( 4) and ( 5) and the three indicators shown in Figure 7, were chosen as the micro-texture evaluation indicators of coarse aggregates.…”

This research aims to improve the durability of skid resistance of asphalt pavement from the perspective of coarse aggregates based on on-site investigation. Firstly, the skid resistance of six representative actual roads was tested during two years by employing the Dynamic Friction Tester and the attenuation characteristics of skid resistance of different types of asphalt pavements were analyzed. Secondly, core samples were drilled onsite and coarse aggregates were extracted from the surface layer of the core samples. The morphological parameters of coarse aggregates were collected by a “backlighting photography” system and three-dimensional profilometer, and the variation rules of angularity and micro-texture of coarse aggregates were investigated. Finally, the correlation between the morphological characteristics of coarse aggregates and the pavement skid resistance was established based on the grey correlation entropy. The research results show that with the increase in service time, the attenuation rate of skid resistance of asphalt pavement gradually slows down; the angularity of coarse aggregates gradually decreases, and the micro-texture on the wearing surface gradually wears away. The grey correlation entropy between all the micro-texture indexes of coarse aggregates and dynamic friction coefficient, as well as between the roundness and skid resistance is more than 0.7, whereas the correlation between other evaluation indicators and the dynamic friction coefficient is poor, indicating that compared with the angularity of coarse aggregates, the micro-texture affects the skid resistance of actual asphalt pavement more greatly. In engineering applications, the use of coarse gradation, coarse aggregates with high roughness or high anti-wear performance can slow down the attenuation of pavement skid resistance, so that the pavement can maintain superior long-term anti-skidding performance.
