The influence of deformation by equal-channel multiple-angle pressing and of thermal treatment on phase composition, state of structure and current-carrying capacity of NbTi alloy superconductor have been studied. Deformation is shown to result in the decreasing of subgrain size (100.88200 nm). In the temperature range to 450 ℃, the used structure was found thermally stable. This is explained by precipitation of disperse particles of the second α-phase at the subgrain boundaries. After the deformation there was a distinct increase in magnetization of the alloy due to magnetic flux fixing at boundaries of crystallites and at α-phase precipitations.
