摘要

Dense MgB2 wires were successfully fabricated through the in-situ powder-in-tube (PIT) method by using steel sheath with low carbon content. Short samples of MgB2/Fe wires were sintered at 650-850°C for 2-5 hours in argon. Critical current density(Jc) of the wires was measured at 4.2K in the magnetic field up to 8 T by standard four probe method. High Jc values of 2.1 × 105 A/cm 2 in 3T at 4.2K were obtained for MgB2/Fe wires. The microstructure observation for MgB2 wires showed that no reaction between Fe and MgB2 was found and MgB2/Fe wires had better grain connectivity. The results indicated that the Jc can be further improved to meet the requirement for applications by optimizing the process conditions.
