Hydride phases of Y₃Al₂, namely Y₃Al₂H_6.5 and Y₃Al₂H_2.2, were newly formed. Y₃Al₂ was hydrided to Y₃Al₂H_6.5 at 373 K and 3.0 MPa of hydrogen, and Y₃Al₂H_6.5 was dehydrided to Y₃Al₂H_2.2 up to 873 K at 0.1 MPa of helium. Furthermore, partial reversible hydriding/dehydriding reactions between Y₃Al₂H_6.5 and Y₃Al₂H_2.2 were confirmed for the first time in the Y-Al system.
