Investigation of Interaction of Alloy Y2MgNi9 with Hydrogen and Ammonia
https://doi.org/10.15518/isjaee.2016.19-20.054-061
Abstract
The alloy consisting of 90% of phase Y2MgNi9 (structural type PuNi3) and 10% of phase YNi5 was prepared. The interaction of alloy with hydrogen and ammonia at different temperatures was investigated. In system Y2MgNi9–H2 at temperatures from –30 to +10 °C the isotherms of hydrogen sorption and desorption were constructed, the formation of two hydride phases was established and the changes in enthalpy and entropy of phase transitions were calculated. The phase transformations at treatment of the alloy Y2MgNi9 with ammonia at temperatures of 200–400 °C were discovered.
