Abstract
A conductor has been prepared, consisting of Niobium and an outer layer of the A15-phase Nb-Al and Nb-Al-Ge respectively. The process involves two steps: Coating of Niobium by hotdipping and subsequent heat treatment. The procedure, the products of reaction and data on the transition temperature Tc and the critical current density J c of the A15-phase are reported. The maximum values obtained for Tc and J c are 18.5 K (19.3 K) and 5 · 104 A/cm2 (2 · 104 A/cm2) at 5 T and 4.2 K for Nb3Al (Nb3Al, Ge).Keywords
