Paper Title:
Effect of Doping, Composite Geometry and Diffusion Annealing Schedules on the Structure of Nb3Sn Layers in Nb/Cu-Sn Wires
  Abstract

Kinetics of formation of superconducting Nb3Sn layers and the structure of bronzeprocessed Nb/Cu-Sn composites with Zr, Zn or Mg-doped matrixes or Ti-doped Nb filaments of different geometry have been studied by the methods of TEM, SEM and electron-probe microanalysis. All the doping elements have been found to accelerate the rate of growth of the diffusion Nb3Sn layers and consequently their thickness. Correlation between the diffusion annealing schedules, the geometry of Nb filaments, the structure of the diffusion Nb3Sn layers and the current-carrying characteristics of multifilamentary Nb/Cu-Sn composites has been established.
