Investigation of inter-grain critical current density in Bi2Sr2CaCu2O8+d superconducting wires and its relationship with the heat treatment protocol
I. Pallecchi, A. Leveratto, V. Braccini +2
In this work we investigate the effect of each different heat treatment stage in the fabrication of Bi2Sr2CaCu2O8+d superconducting wires on intra-grain and inter-grain superconduc…
New concept for the development of Bi-2212 wires for high field applications
Andrea Malagoli, Alessandro Leveratto, Valeria Braccini +2
The first step towards high critical currents in Bi-2212 wires was the comprehension that the supercurrent is blocked over long lengths by filament-diameter bubbles grown during th…
Groove-rolling as an alternative process to fabricate Bi-2212 wires for practical applications
Andrea Malagoli, Valeria Braccini, Maurizio Vignolo +2
Bi2Sr2CaCu2O8+x (Bi-2212) superconducting long-length wires are mainly limited in obtaining high critical currents densities (JC) by the internal gas pressure generated during the…
Large critical current density improvement in Bi-2212 wires through groove-rolling process
Andrea Malagoli, Cristina Bernini, Valeria Braccini +4
Recently the interest about Bi-2212 round wire superconductor for high magnetic field use has been enhancing despite the fact that an increase of the critical current is still need…
Study of the MgB2 grain size role in ex-situ multifilamentary wires with thin filaments
A. Malagoli, V. Braccini, C. Bernini +4
The MgB2 superconductor has already demonstrated its applicative potential, in particular for DC applications such as MRI magnets, thanks to the low costs of the raw materials and…
