The effects of annealing time and temperature on the structure and superconducting characteristics (critical current and superconducting transtormation temperature) of Nb-Ti alloys are studied individually. Heat treatment raises the critical current density of cold-worked alloys. The maximum critical current density is achieved in a Nb-75%Ti alloy (105 A/cm2 in a field of 26 kOe) after annealing at 450° (for 1 h in final annealing or 10 h after intermediate annealing). The transtormation temperature rises to 8.6°K in the annealed alloys. The effect of heat treatment on the superconducting characteristics is associated with the decomposition of the original β solid solution of the cold-worked Nb-Ti alloys.
