Investigation on structure and properties of superconducting internal tin wire to be used for high field magnetic systems

Main stages of diffusion interaction between tin alloy with copper matrix and the material of Nb filaments in superconductors with 1 central and 7 distributed tin sources, containing 2000 to 14000 filaments have been investigated. The main temperature conditions for intermediate and final heat treat...

Summary:Main stages of diffusion interaction between tin alloy with copper matrix and the material of Nb filaments in superconductors with 1 central and 7 distributed tin sources, containing 2000 to 14000 filaments have been investigated. The main temperature conditions for intermediate and final heat treatment stages have been chosen. Tin distribution over a copper matrix cross section has been shown not to exceed 2% at optimum heat treatment conditions. The conductor's current carrying capacity interconnection with heat treatment routes has been studied. It was shown that the correct choice of a heat treatment route provides for high values of critical current density upto 1/spl times/10/sup 5/A/cm/sup 2/ (12 T).< >
