Superconducting composites are widely used in many industrial applications especially in electrical power transmission because of their amazing properties. The achievement of optimal performances (high critical current density and appropriated mechanical properties) requires a deep knowledge of the processing parameters of silver sheathed Bi-2333 composite tapes and copper sheathed MgB2 composite wires and tapes. In the PIT method each deformation step should be understood and controlled to insure the results of the whole process. Different mechanical deformation routes are possible in the...
