Abstract
In this paper, microstructure and hydrogen storage characteristics of TiMn2−XVX alloys were investigated by means of XRD, SEM, metallography and PCT tests. XRD tests showed that with the increase of V content the phase composition of these alloys changed from coexistent V based BCC phase and Laves phase to single V based BBC phase. Segregation of both V and Mn was weakened, simultaneously. Hydrogen storage capacity of these alloys increased with increasing V content. Both enthalpy change and entropy change of hydrogen absorption were augmented accompanied with the enhancement of hysteresis between hydrogen absorption and desorption.
