Preparation and characterization of biaxially textured metallic substratesfor HTS coated conductors

CuNi NiCr, NiV alloys and pure Ni have been processed to obtain metallic su bstrates for high critical current density YBCO film depositions. High puri ty alloys were prepared using plasma are furnace and the material was cold rolled to low thickness tapes. For all the tapes the (100)[001] cube alignm ent was induced by a primary recrystallization heat treatment after heavy c old rolling (RABITS). Besides the cube texture a good substrate should be s mooth, thin, strong non magnetic, resistant to oxidation, cold workable and low cost. In this work mechanical magnetic and oxidation resistance proper ties of the prepared textured substrates were measured and compared.
