Abstract :
The improvement of mechanical and magnetic properties of textured NiW alloy tapes are considered as a main challenge for RABiTS substrates in coated conductors. The present paper summaries the successful development of several textured NiW substrate tapes with high W contents as well as advanced NiW composite substrates with high strength and reduced magnetization. The fabrication processes of these tapes and their characterizations are presented in detail. The results on the texture quality and mechanical properties as well as on the magnetic behaviors of these tapes are promising in view of the future application in coated conductor and constitute an alternative to the well known Ni5W RABiTS substrates.
