英文摘要	This work studied the characteristics of the microstructure of industrial electrolytic nickel deposits changing with deposition time. Using XRD, SEM, EBSD and other analysis methods, the preferred orientation, microstructure and characteristic grain boundary distribution of electrolytic nickel plate with the deposition time were studied. The results show that the crystals on the surface of the electrodeposited nickel plate mainly grow in the direction perpendicular to the (200) plane, the cross-section shows the (111) and (200) double preferred orientations, and the crystal growth method is lateral growth. The surface and the cross-section show different microstructures. The surface morphology changes from a pyramid shape to a cell shape and the growth mechanism changes from spiral dislocation-driven growth to atomic aggregation and accumulation. The cross-sectional morphology of the nickel plate is always a lamellar structure at each stage. The cross-section of the deposited layer is mainly high-angle grain boundaries and a large number of Σ3 twin grain boundaries. In the stable growth process, the proportion of large-angle grain boundaries gradually decreases as the deposition progresses, nevertheless the relative frequency of Σ3 grain boundaries gradually increases, but they will all be affected by changes in the environment of the electrolytic cell. In the cross-section along the growth direction, the electrolytic nickel plate mainly shows the fiber texture of direction, and a large number of Σ3 twin boundaries affect the orientation of the deposited layer. By increasing the ratio of Σ3 twin boundaries or selecting the electrolytic nickel corresponding to the higher frequency of Σ3 twin boundaries, electrolytic nickel with better strength and plasticity can be obtained. The evolution law of the electrolytic nickel deposition layer has been clarified, which means that the micro-control of the electrolytic nickel organization can be carried out in the later research or the guidance of industrial production, and the customized production of electrolytic nickel under industrial conditions can be realized. © 2022, Science Press.
