MULTI-LAYER TAPE NANOSTRUCTURE COMPOSITE BASED ON SUPERCONDUCTING NIOBIUM-TITANIUM ALLOY

摘要

FIELD: physics; conductors.;SUBSTANCE: invention relates to making composite superconductors with improved current-carrying capacity and can be used, particularly, for making superconducting magnet windings. According to the invention, the multi-layer tape nanostructure composite based on a superconducting niobium-titanium alloy contains alternating layers of niobium and niobium alloy-(25-45) wt % titanium, with layer thickness of not more than 50 nm. The thickness of each niobium layer is 50-70% of the alloy layer thickness.;EFFECT: obtaining a composite with critical current density of 58000 A/cm² in a magnetic field with flux density of 6 T.;2 cl, 3 tbl
