Abstract

Sharp cube textured Ni-9%atW alloy substrates were successfully achieved using the powder metallurgy process and gave promise for coated conductor with reduced AC losses and improved mechanical properties. X-ray studies Indicated that the newly developed Ni-9%atW alloy substrates have a good out-of-plane and in-plane orientation with FWHM values about 3.7° and 7.05° respectively. Smooth surface as well as fine grains were obtained in the newly developed textured substrate. Curie temperature is suppressed to be 30 K and magnetic hysteretic losses are zero for Ni-9%atW alloy substrates at 77 K.
