摘要:
In-situ MgB2/Fe tapes were fabricated by powder-in-tube (PIT) technology using Mg and B powders. The tapes were sintered by advanced spark plasma sintering (SPS) technique. The effects of the annealing parameters on the properties of the MgB2 tapes were investigated by the analysis of XRD, SEM and the magnetic J(c) measurements. It was shown that at 10 K, 0 T, the J(c) value of the tape sintered using SPS machine at 800 degrees C for 15 min under 40 MPa was close to 106 A/cm(2), which was higher than that of the same tapes annealed by conventional method. It was supposed that the density and the homogeneity of the MgB2 core were strongly improved using fast SPS sintering process. Further enhancement of J(c) in the tapes is expected for the understanding of the SPS sintering mechanism. (c) 2007 Elsevier B.V. All rights reserved.
