Abstract :
A sharp cube textured alloy substrates with high strength and low magnetism are required in coated conductors´ applications. In this work, the cube textured Ni-7at.%W substrates, starting from advanced powder metallurgy ingots followed by Rolling Assisted Biaxially Textured Substrate (RABiTS) method, have been prepared. The fabrication processes of Ni-7at.%W tapes with sharp cube texture by spark plasma sintering(SPS) routes were described. By Electron Back Scattering Diffraction (EBSD) analysis, the percentage of the cube texture component in Ni-7at.%W tape surface is found to reach 99.4% within a misorientation angle smaller than 10deg . Moreover, the formation mechanism of the cube texture in the Ni-7at.%W tape was also investigated by EBSD. Particular attention was focused on the difference of the texture components along the thickness of the partially recrystallized samples.
