Texture, structure and properties of Ni-based binary alloy tapes for HTS substrates

Abstract

Abstract Depending on the contents of alloying elements (Nb, up to 5.4 at.%; W, up to 7.4 at.%; Re, up to 4.1 at.%; Mo, up to 9.5 at.%; V, up to 10.1 at.%; Mn, up to 22.1 at.%; Al, 12.0 at.%; and Cr, up to 22.0 at.%) texture, structure, and physical and mechanical properties are studied in thin tapes that serve as substrates for epitaxial deposition of a high-temperature superconductor on the nickel-based binary alloys. The upper limit of alloying element content is established at which sharp cube texture of primary recrystallization is feasible to be formed. It is shown that such boundary concentration of alloying elements is associated with a certain quantitative ratio between the deformation texture components and with a certain magnitude of the concentration expansion of lattice parameter. Some mechanical and physical properties of alloys with cube texture are determined.
