Four-filament ex and in situ MgB2 wires were prepared with the rectangular wire-in-tube (RWIT) technique. Based on experience with single-core wires, 10 wt% of W was added to the ex situ and 10 wt% of SiC to the in situ powders, which were packed into Fe and Nb/AgMg tubes, respectively, and two-axially rolled into composite conductors. The ex and in situ conductors are compared in terms of field-dependent transport critical current density, effects of filament size reduction and twisting, mechanical behaviour and thermal stability.
