Abstract

By employing the technique of transmission electron microscopy we studied the effects of plastic deformation on diffusional decomposition processes in the alloy of NT-50 type (Nb-48±1.5wt%Ti). The studies were performed on 1-, 210-, 8.910-filament samples with an appropriate higher level of plastic deformation. Isothermal anneals were carried out in a wide range of treatment durations. The critical current density on multifilamentary composite specimens was measured in various magnetic fields. An optimum Jc is analyzed in the aspect of the magnetic pinning mechanism.
