Precipitous change of the irreversible strain limit with heat-treatment temperature in Nb 3 Sn wires made by the restacked-rod process

The intrinsic irreversible strain limit ε of Nb Sn superconducting wires, made by the restacked-rod process and doped with either Ti or Ta, undergoes a precipitous change as a function of temperature θ of the final heat-treatment for forming the A15 phase. Nb Sn transitions from a highly brittle sta...
