摘要：

Explosive cladding, subsequent rolling and heat treatment are employed to fabricate a composite (sandwich) strip consisting of an intermediate high temperature superconducting ceramic layer of the Bi-Pb-Sr-Ca-Cu-O compound and two metal silver plates. Macro- and microstructural experimental observations regarding the quality of the product at the various stages of the fabrication were evaluated using optical and scanning electron microscopy and X-ray diffraction techniques, whilst the superconducting properties of the composite strips were obtained using ac-magnetic susceptibility techniques; preliminary dc-resistivity measurements were made also to evaluate further the superconductive properties of the material. Post-fabrication heat-treatment in air resulted in improved superconductivity of the heat-treated strips as compared to the residual superconductivity obtained after rolling, leading therefore to useful conculsions regarding the applicability of the fabricated composite plates in the electrical and electronic industries.
