Abstract
Effect of mechanical activation on the structural transformations in zirconium - graphite - hydrogen system was studied using X-ray powder diffraction, scanning and transmission electron microscopy and kinetic techniques. Experiments with zirconium - graphite mixture were carried out under high-energy impact milling in a permanent hydrogen flow. Mechanically induced process of two stages was observed: (1) formation of the tetragonal ε-ZrHx (x = 1.8-2); (2)
