Abstract

Transmission electron microscopy and electron back-scattered diffraction (EBSD) analysis have been used to study the microstructure of the YBa2Cu3O6.8 compound, which is formed during low-temperature heat treatment in a humid atmosphere and after restoring annealing at T = 930°C. It has been shown that structural defects formed after annealing at 200°C remain after short annealing at 930°C and can serve as pinning centers that favor the improvement of critical characteristics of the material. The restoration of the initial structure is accompanied by the recrystallization of the material.
