“…The average surface microhardness of the SGP sample is 354.5 HV, which is 143.1 HV and 33.7 HV higher than that of the untreated and SP samples, respectively. In addition, the mixed strengthening abrasives, comprising zirconia ceramic balls, brown corundum powder, and strengthening liquid, used in the SGP treatment were more beneficial for improving the impact kinetic energy and contest stress than those zirconia ceramic balls that were used in the SP treatment [ 41 ]. Therefore, a higher microhardness is obtained in the SGP sample for the reason that the SGP treatment exhibits a stronger work hardening capacity than that of the SP treatment.…”

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.

“…The surface treatment that only considered ceramic balls was named USP, and mixed white corundum and the ceramic balls was named DUSGP. The other one that mixed white corundum and ceramic ball, as well as strengthening liquid was named WUSGP [35]. The strengthening liquid was composed of extrusion additive (i.e., C10H14N2Na2O8•2H2O), triethanolamine (C6H15NO3) and water.…”

In this paper, the corrosion resistance of four GCr15 steel samples has been investigated. Three samples were initially surface-treated by ultrasonic shot peening (USP), a dry ultrasonic strengthening grinding process (DUSGP), and a wet ultrasonic strengthening grinding process (WUSGP), respectively, while another one was only polished. Then, all the processed samples were subjected to salt spray corrosion. Sample properties, such as capacitance arc, self-corrosion potential (Ecorr), self-corrosion current density (Icorr), corrosion morphology, and corrosion products were analyzed. Results show that the sample treated by WUSGP has the best corrosion resistance, which can be attributed to the high dislocation density, small grain size, needle-like and lath-like shape of martensite content formed in the treatment, which hinders Cl− from eroding the matrix. The obtained corrosion pits and cracks in Sample WUSGP show a width of approximately 1.4 µm and 2.1 µm, respectively, degrading 78% and 75% compared to polishing. The possible corrosion mechanism of the samples has been discussed. The findings denote that the treatment fused ceramic balls, strengthened liquid, and corundum in USP could be an efficient method to improve the corrosion resistance of some mechanical parts.

“…nesterenko et al also proposed a dynamic recrystallization model based on rotation [6]. The metal material has a bamboo-like elongated deformation substructure under high-speed deformation and large strain [12,13], and the boundary of the orientation angle with the lowest boundary energy can be diffused to transform the deformed substructure into dynamic recrystallized grains with equiaxed microscopic orientation angles [14]. however, this process requires the matrix atoms to diffuse from the original boundary to a nearby location and form a new grain boundary, which is difficult to achieve in the view of material dynamics [15].…”

Microstructure evolution MechanisM of aisi 1045 steel under high speed deforMationaiSi 1045 steel has the characteristics of high strain rate, large strain, and sharp rise in temperature during high-speed deformation process, resulting in a concentrated deformation band and fine structure. in this work, the microstructure of submicron-sized grains in aiSi 1045 steel material formed under 10 6 s -1 during a high speed cutting process was examined. To reveal the dynamic evolution mechanism of the aiSi 1045 microstructure, the continuous dynamic recrystallization theory was introduced. The results show a high dislocation density which favor the formation of small angle grain boundaries during the high speed cutting process. Kinetics calculations that use continuous dynamic recrystallization mechanisms prove that the recrystallization size is constant when the strain rate increases from 10 3 s -1 to 10 6 s -1 , and the transition time is reduced from 6×10 -5 s to 4×10 -8 s. The recrystallization grains were gradually formed during the deformation of the material, not generated after the deformation.
