Absorption of hydrogen by V-Mo and V-Mo-Ti alloys

We have studied the interaction of hydrogen with V-Mo and V-Mo-Ti alloys. Hydrogen absorption and desorption isotherms have been measured, the stability ranges of the forming hydride phases have been determined, and the ΔH and ΔS of the reactions involved have been calculated. X-ray diffraction results indicate the formation of three hydride phases, with FCC and BCC structures.
