Abstract
In order to obtain high T-c superconducting materials with improved mechanical properties, Bi-1.5 Pb0.5Sr2Ca2Cu3Ox/ Ag-composites with three different filler morphologies (particulates, whiskers, wires) were successfully synthesised. It is shown that Ag-addition improves Bi-2223 grain growth and reduces sample-porosity, Composites exhibit increased ductility and isostrain conditions are met. The mismatch in thermal expansion coefficient induces a residual stress field at the filler matrix interface which allows toughening mechanisms to appear, resulting in a clear post-peak behaviour, The continuous unidirectional composites are the most successful for improving mechanical properties.
