Abstract:The cube textured Ni-7%W substrates were prepared by spark plasma sintered (SPS) ingot, followed by rolling-assisted biaxially textured substrate (RABiTS) processing. The grain orientation data and the grain boundaries information of the Ni-7%W(Ni7W) substrate were collected by electron backscatter diffractometry (EBSD). The texture of the Ni7W substrate was analyzed. The high quality of EBSD image is observed on the sample surface after annealing process without polishing. The Ni7W substrate forms a sharp cube texture, and the mass fraction and length fraction of the cube texture grains in the Ni7W substrate reach 99.4% and 93.6%, respectively, within tolerance angle smaller than 10˚.
Key words: Ni-7%W substrate (Ni7W); cube texture; coated conductor
