Abstract: The Ti sheet Nb sheet and Ta sheet were arranged as periodical order of …TiTaNbTaTi….The NbTiTa/Cu composite was produced after four hot extrusions,and then the composite was alternately drawn and heated at 420 ℃ for 40 h,50 h,60 h and 70 h,respectively.The critical current density at 3.0 K and 4.0 K increases remarkably with the increase of final strain.The critical current density of the wire with diameter 1.25 mm at 3.0 K and 11 T is 350A/mm2,which can show that the NbTiTa/Cu superconducting ... More
