Effect of deformation-thermal processing using equal-channel multiangle pressing and low-temperature drawing on the superconducting properties of niobium-titanium alloys.

The effect of combined deformation, including equal-channel multiangle pressing (ECMAP), lowtemperature (77 K) drawing, and thermal processing, on the critical current density of superconducting wires based on Nb-Ti alloys is investigated. Reasonable parameters are established for deformation-thermal processing of NT-50 alloy using ECMAP that will ensure improved functionality of superconductors based on this alloy. Vortex pinning on structural inhomogeneities of these alloys is analyzed qualitatively. [ABSTRACT FROM AUTHOR]
