Abstract

The structure of a massive MgB₂ compound deformed by upsetting at room temperature and then annealed at 650°C has been investigated by X-ray diffraction analysis, scanning and transmission electron microscopy. The obtained material is characterized by a dense nanosized structure of the matrix MgB₂ phase with good intergrain bonds and a uniform distribution of dispersed MgO inclusions.
