STRUCTURE AND SUPERCONDUCTING PROPERTIES OF YBa*002Cu*003O*007*00-*00x HOT DEFORMED CERAMICS

Abstract

The systematic investigation of the mechanical behaviour, microstructural modifications, superconducting properties of polycrystalline ceramics after the hot plastic deformation and thermal treatment is the aim of the paper. As a result microstructural modifications, taking place in a material at the hot deformation have been investigated. The interconnection between structural modifications and superconducting properties has been established. The method of the hot deformation of YBa*002Cu*003O*007*00-*00x extrusion, method making it possible to obtain longitudinal articles with various microstructures, has been developedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
