Title: Superconducting Wires Of Cu-nb3sn: The Liquid-phase Sintering Method
Author: De Lima O.F.
De Rezende A.T.
Abstract: A new method aimed at obtaining Cu-Nb3Sn wires in a simple and low cost way is introduced. A powder mixture of Cu-30 wt% (Nb-H)-0.3 wt% Al was degassed and heat treated (T=1200° C) under vacuum, leading to soft, highly dense Cu-Nb sintered samples. Tin diffusion and reaction resulted from external and internal processes. In the latter case cores of tin-rich alloy were used, but an intrinsic drawback related to the occurrence of hard η-phase precipitates can be identified. The critical temperature, critical current density, and normal electrical resistivity at 19 K are analysed and correlated with the other parameters (e.g. reaction time and Cu/SC ratio). © 1986 Chapman and Hall Ltd.
