Mechanically reinforced MgB2 wires and tapes with high transport currents
Monofilamentary MgB2-wires with a 2- or 3-component sheath containing
mechanical reinforcing stainless steel (SS) were prepared and characterized. In
direct contact to the superconductor Nb, Ta or Fe was used. For a selection of
samples with a Fe and Fe/SS sheath, we investigated the transport critical
current behaviour in magnetic fields changing systematically the geometrical
shape from a round wire to a flat tape. A strong increase of the current
densities in flat tapes was observed and possible reasons for this are
discussed. Reinforcing the sheath in the outer layer with different amounts of
stainless steel leads to a systematic field dependent decrease of the transport
critical current density with increasing steel amount. This is an indication
for a pre-stress induced degradation of the critical currents in MgB2 wires and
first Ic-stress-strain experiments seem to confirm this observation and
interpretation.Comment: 12 pages, 5 figures. Submitted to Physica C (Proceedings of EUCAS
