Abstract

Superconducting compound Nb3Al was obtained as a result of thermal treatment of triple-layered Nb/Al/Nb and multilayered Nb/Al ribbons. The effect of copper on superconducting characteristics of Nb3/Al diffusive layers formed in Nb/AlCu/Nb composite was studied. The possibility of producing the β (Nb3Al) phase via diffusion at temperatures below 1000°C was shown. However, superconducting properties of these ribbons were low. The best superonducting properties had multilayered niobium or duralumin ribbons after heating at 1700°C for a few seconds.
