Investigation of Hydrogen Sorption Properties of TiMn2 Based Alloys
Microprobe analysis and X-ray powder diffraction were performed for a series of intermetallic compounds Ti0.95Zr0.05Mn1.45M0.5where M = V, Cr, Mn, Co, Ni and Al. These compounds crystallize in the hexagonal C14-t...

A hydriding kinetic model of the Mg2Ni-H2 system
The hydriding kinetics of an Mg2Ni alloy are investigated under hydrogen pressures from 2.5 to 8 bar (0.25 to 0.8 MPa) at various temperatures (543 ⩽T ⩽ 583 K). The hydriding reaction of Mg2Ni progresses by a nuc...

Hydriding mechanism of Mg2Ni in the presence of oxygen impurity in hydrogen
For the case where oxygen is present as an impurity in hydrogen, a hydriding mechanism is proposed along with hydriding cycling of the Mg2Ni alloy. The large chemical affinity of magnesium for oxygen leads to the...
