Preparation and Characterization of Cube-Textured Ni-5 at.% W Substrates for Coated Conductors

Article Preview

Abstract:

The goal of present study was to manufacture and characterize the Ni-5 at.% W alloy substrates for coated conductor applications with a strong cube texture. Cube-textured Ni-5 at.% W alloy substrates were fabricated by heavy cold rolling (98%) and a high temperature annealing (1200°C). From the EBSD and XRD analysis of the fully recrystallized tapes, the cube texture component in the tape was found to reach a proportion as high as 99.5% within a tolerance angle of less than 9o, while the FWHM (full width at half maximum) values of the out-of-plane and in-plane textures are about 5.8o and 6.9o, respectively. Moreover, the grain size distribution is homogeneous, and there is a large amount of low angle grain boundaries (95.6%). This process is very suitable for preparation of substrates for coated conductors.
