Abstract

The effects of axial tensile and bending strains on the critical current densities of Ag and AgNiMg/Bi-2212 wires produced by the powder-in-tube method have been studied. The observed degradation of the critical current density due to strain effects is irreversible and can be attributed to the formation of microcracks within the superconducting core. This seems to be determined by the residual thermal strains. The mechanical properties of the composite wires at 4.2 K are also presented.
