“…SPD imposes higher magnitude of strain leads production of ultrafine-grained and nanostructured materials [3]. CGP as one of the applicable techniques, imposes repetitive shear strain by alternate pressings of grooved and flattened dies [4,5]. Besides, rolling is applied for continuous production of bulky materials.…”

“…Micro-shear bands developed due to inhomogeneous strain distribution were observed in the deformed structure, as shown in Figure 4. The shear-band formed under surface micro-crack facilitated crack propagation between the less and more work-hardened regions corresponding to microstructures basically including equiaxed and elongated grains, respectively, indicated by the white arrow [26]. It has been revealed that the change of deformation mode as well as the localized plastic deformation during CGP led to deformation marks appearing at the sheet surface and serving as sites of stress concentration [18].…”

Constrained groove pressing (CGP) is one of the most promising severe plastic deformation (SPD) techniques suitable for producing ultra-fine grained (UFG) sheet or plane metallic materials with unique physical, chemical, and mechanical properties. However, the heavily deformed sheets are usually with high strength but low ductility due to work hardening and micro-cracking, and the UFG microstructure and high strength are unstable especially when exposed to high temperatures. Thus, in this work, CGP was conducted on commercially pure nickel sheets and, firstly, the fracture mechanism of the processed sheets was examined. Then, the annealing behavior of CGP nickel sheets was investigated in detail to explore their thermal stability and improve their ductility. The results showed that significant grain refinement and strength improvement of the nickel sheets were achieved with great loss of ductility. The fracture surface morphology of the sheet sample exhibited typical characteristics of fatigue fracture, and inhomogeneous strain distribution and work hardening determined the micro-crack initiation position and propagation direction. The CGP sheets by one and two passes showed high thermal stability up to 650 and 600 °C, respectively, owing to different stored internal stresses and accumulated energy. In both cases, obvious recovery of elongation to failure from 12.7% and 10.6% to 29.3% and 27.3% were achieved by CGP with post-deformation annealing treatment, respectively, with acceptable drop of strength.

“…Besides arc welding, resistance spot welding has been applied to join aluminum and steel, but the short electrode life was the concern [7,8]. Analysis of X-ray diffraction results revealed that post-rolling of constrained groove pressed sheets induced dynamic recrystallization due to massive dislocations' accumulation, which is followed by crystallite growth [9]. Compare to gas metal arc welding, Cold Metal Transfer (CMT) welding was widely applied in dissimilar metal welding because of the characteristics of low heat input, free of splashing and strong bridging ability [10].…”

In this paper, cold metal transfer (CMT) plug welding of aluminum AA6061-T6-to-galvanized DP590 steel is studied using AlSi-5 welding wire as filler material. The influence of wire feeding speed on welding quality is one of the research emphases. Firstly, an orthogonal experiment is designed to investigate the impact of wire feeding speed, welding speed and arc length correction on the mechanical performance of the joints. In addition, the welding quality of weldments under optimized process parameters are examined by tensile test and metallographic test. Finally, the influence rule of joint shape, metal transition thickness and welding strength under different wire feeding speed is studied. The results show that wire feeding speed has the greatest influence on joint strength. When wire feeding speed goes up from 5.0 m/min to 6.2 m/min, the thickness of intermetallic transition layer increases. The optimal combination of process parameters is analyzed.
