Resumen:
The presence of texture in Ti sheathed MgB2 cables, induced by the manufacturing process, have been evaluated using XRD polefigures. Drawn monofilamentary and rolled multifilamentary cables have been compared in order to determine the effect ofdifferent deformation degrees arising from the thermo-mechanical treatments. Finally, the critical current density of the cables(Jc) was evaluated using a SQUID magnetometer. We found that MgB2 {101ത0} planes align with the AD direction after drawing,while after rolling, this alignment is not present. The Jc ratio between parallel and perpendicular field is larger for themonofilamentary than for multifilamentary wires, which may be correlated with the differences in the MgB2 texture betweenthese samples.
