Optimization of FeSe Superconducting Tapes with Different Sheath Materials and Precursor Powders

Abstract

FeSe superconducting tapes with different sheath materials of Nb/Cu composite, Ag, and Fe have been fabricated with a traditional in situ powder-in-tube (PIT) process, respectively. With the same cold working process and heat treatment, the influences of different sheath materials on the phase composition and microstructures of FeSe filaments have been analyzed. Due to the reaction between Nb-Se and Ag-Se, Nb2Se and Ag2Se particles can be clearly observed embedded in the filaments. Therefore, it is necessary to introduce a new method for the fabrication of Ag or Nb sheath FeSe wires in order to avoid the introduction of metal Fe in magnet system during practical applications. Based on our previous study, a high-energy ball milling process has been performed to achieve precursor powders with amorphous FeSe binary compound instead of elemental Se. The formation of Ag-Se compounds has been successfully avoided and the superconducting tapes with high superconducting FeSe critical temperature of 9.0 K have been obtained.
