Fabrication of non-magnetic and cube textured Ni-12%V alloy substrate used for coated conductors by melting route

A non-magnetic and high cube textured Ni-12%V(Ni12V,mole fraction) alloy substrate was developed by melting method.The fabrication processes of this tape and its essential characterizations were presented.The influence of hot rolling process before the large deformation on deformation texture of initial ingots was investigated by rolling technology.The results show that,after the optimized recrystallization annealing method,the cube texture content(10°) as high as 97.2% and the fraction of small angle(10°) grain boundaries as high as 80.8% are obtained in the Ni12V tape.The hot rolling before cold rolling is effective to improve the cube texture content,which is expected to provide a theoretical basis for fabricating other nickel-based alloy substrates.
