Abstract

Ti₄₅ Zr₃₅ Ni₁₇ Cu₃ amorphous and icosahedral quasicrystalline (I-phase) powders were synthesized by mechanical alloying (MA) and subsequent annealing, the phase structure and hydrogen absorption properties of two powders were investigated. XRD analysis indicated that the MAed powder was an amorphous phase and annealed powder was an I-phase. Two alloy exhibited excellent hydrogen adsorption property and started to absorb hydrogen without induction time. PCT measurement showed that the plateau pressure of the amorphous powders was obviously higher than that of the I-phase powders. After the first hydrogen cycling, the partial amorphous phase changed to (Zr, Ti) H₂ phases, and the I-phase was steady. Similar hydride phases Ti₂ ZrH₄ and (Zr, Ti) H₂ were also formed after the second hydrogen cycling for the amorphous and I-phase alloy powders.
