Abstract
Mass-spectrometric investigations of hydrogen liberation from the mixture of powders 3ZrO0.2Hx + ZrFe2, the overall composition of which corresponds to Zr4Fe2O0.6Hx, after its treatment by ball milling for 5 and 50 h show a substantial dependence of hydrogen desorption on the time of mechanical treatment. X-ray phase analysis demonstrates a significant disordering of the structure of components after high-energy ball milling. The combination of mechanical treatment and hydrogen desorption from the prepared mixtures does not lead to the formation of the Zr4Fe2O0.6 intermetallic phase as was observed during desorption-recombination in the HDDR process.
