Hydrogen induced structural phase transformation in ScNiSn-based intermetallic hydride characterized by experimental and computational studies

“…Investigations of hydrogen interaction with Sc-containing intermetallic phases were limited to the studies of the hydrogen interaction with Laves type ScT 2 intermetallics (T= Fe, Co, Ni, Mn) [17][18][19]. These studies showed that hydrogen storage capacities and thermal stabilities of the Sc-containing Laves type hydrides are lower as compared to the RE-containing analogues.…”
