The evolution of microstructure and texture at four strain levels was investigated in Ni-5 at％ W alloy by means of electron backscatter diffraction (EBSD) technique.The deformation microstructure evolves gradually from microbands (MBs) to typical lamellar structures with strain increasing in cold-rolled materials,while only lamellar structures in heavily cold-rolled materials.Subsequently,quantitative analysis of microstructure and texture was performed.It indicates that the texture is a typical pure metal deformation texture,but a few cube and rolling direction (RD)-rotated cube orientations also can be observed in the deformed samples.The use of high-temperature annealing enables an area fraction of cube orientation ＞ 95％ to be obtained for high strained substrate.In addition,it is worth noting that the point-to-point misorientation inside the band with various orientations is found to keep quite low.But the point-to-origin misorientation over the same distance is dependent on strain and orientation type in the band.The cube-oriented regions were characterized by a high accumulated orientation gradient,close to 28°,compared to the non-cube-oriented regions.This means that the accumulated orientation gradient only occurs in the cube band with the reduction of 98％,which partly explains the formation of strong cube texture after high-temperature annealing.
