Abstract

Abstract:

Experimental alloys with compositions of Mg_25-_xY_xNi₉Cu (x = 0, 1, 3, 5, 7) have been successfully prepared through melt spinning method. The phase compositions and microstructures were measured by X-Ray diffraction (XRD) and high-resolution transmission electron microscopy (HRTEM). The de-/hydrogenation properties were measured by utilizing Sievert apparatus, differential scanning calorimetry (DSC) and thermal gravimetric analyzer (TGA) connected with a H₂ detector. The Arrhenius and Kissinger methods were adopted to calculate their dehydrogenation activation energies. The results show that hydrogen absorption kinetics of the alloys notably decline while their hydrogen desorption kinetics conspicuously improve with spinning rate increasing. The dehydrogenation activation energy markedly decreases with spinning rate increasing, which makes the hydrogen desorption kinetics improve. The thermodynamic parameters (ΔH and ΔS absolute values) clearly decrease with spinning rate increasing. The hydrogen absorption capacity exhibits different trends with spinning rate rising. Specifically, hydrogen absorption capacity increases at the beginning and declines later for Y₁ alloy, but that of Y₇ alloy always decreases with spinning rate growing.
