For practical use it is essential to make Fe-based superconducting materials into wire and tape conductors with sufficient current carrying capability, which is limited by misaligned grains inside the conductors. The development of Fe-based superconducting wires at IEECAS has progressed rapidly resulting in improving the wire performance. A record transport critical current density (Jc) reaching 1.5 ×105 A/cm2 (Ic = 437 A) at 4.2 K and 10 T in Ba0.6K0.4Fe2As2 (Ba-122) tapes by texturing the grain orientation with optimized hot-press technique. The transport Jc measured at 4.2 K under high magnetic fields of 27 T is still on the level of 5.5 ×104 A/cm2. Moreover, at 20 K and 5 T the transport Jc is also as high as 5.4 ×104 A/cm2, showing a promising application potential in moderate temperature range which can be reached by liquid hydrogen or cryogenic cooling. The high-performance PIT Ba-122 tapes in this work suggest iron-based superconductors to be a strong potential conductor for high-field applications.
