Formation of stable superconducting (SC) phase of intermetallid Nb3GexAl1-x (x ≅ 0.2−0.30) by thermal annealing of multi-layer structures Nb/Ge/Al-like specimens under T=1213±20K in vacuum has been ascertained. The multi-layer structures had been made with the method of electrochemical concretion of Ge and Al layers on Nb (Nb is a structural foundation). The critical (Ic) currents that flow inside the specimens under the temperature He in magnetic fields H>>Hc2(Nb) have been measured; the critical densities of current (jc) have been rated. The nature of (jc)-dependence on the time of annealing, magnetizing force H(Tl), layer thickness of Ge -hGe (mcm) (under hAl ≈ const) and the layer thickness of Al-hAl(mcm) (under hGe ≈ const) have been ascertained. A conclusion on technological advisability of the electrochemical-forming method of multi-layer Nb/Ge/Al-lik |
