英文摘要	The mechanical performances and microstructures of the commercial electrolytic nickel plates were studied. In order to explore the mechanical behavior of metal in the plastic deformation, in particular, several cold rolling with different deformations were imposed on the electrolytic nickel plates. The results show that the micro/nanocrystallines with sizes of 0.5 similar to 1.5 gm exist in the electrolytic nickel. At the same time, there are growth twins in the microstructures. The tensile strength of the nickel is from 385 MPa to 461 MPa, and in the vertical direction of the beginning-less product it reaches the lowest (385 MPa), and in parallel direction of the beginning product reaches the highest (461 MPa) and the fracture has a typical plastic dimple fracture morphology, which shows the electrolytic nickel has good plasticity and toughness. For the nickel by cold rolling with 90% deformation, the grain size decreases obviously. The hardness of the metal increases gradually with the increase of deformation, and the work hardening phenomenon exists in nickel metal. The cold rolling process causes the random original grain orientation to prefer to some selected orientations. When the cold rolling deformation reaches 98%, the texture coefficient of crystal face TC(220) is equal to 76.4%, and a deformation texture appears in the (220).
