Description
Data of a single-filament Nb-44.5 Ti superconductor subjected to cyclic deformation by means of reversible torsion are presented. A strong-correlation was observed between the critical current density and the number of deformation cycles realized during the thermo-mechanical treatment. The highest critical current density obtained in the present investigation was 694 A/mm2. This value corresponds to a deformation of the material by 450 to 650 cycles at an amplitude of ± 1.5%. (orig.)
Abstract (German)
Es wird ueber den Einfluss einer zyklischen mechanischen Beanspruchung und der Waermebehandlung auf die kritische Stromdichte bei Supraleitern aus Nb-44,5 Ti-Draehten berichtet. Die hoechste kritische Stomdichte betrug 694 A/mm2. Dieser Wert entspricht einer Verformung des Werkstoffes nach 450-650 Beanspruchungszyklen mit einer Amplitude von ± 1,5%. (orig.)Additional details
