Abstract

The distribution of microconcentrations of Ti in NbTi ingots, produced by various melting methods, are under the consideration. The surface gas saturations are investigated at recrystallization and homogenization heat treatments. The control measures, allowed to reveal billet defects in a process, are described. The 40 µm filament conductor, produced of NbTi billets, manufactured by VNIINM, has jc=3.2 × 105A/cm2and n = 87(5T;0.1 µV/cm).
