The hydrogen storing behavior of C14 Laves-CruFeMnTiVZr, -CrFevMnTiVZr, -CrFeMnwTiVZr, -CrFeMn-Ti(x)V(y)Z(r), -CrFeMnTiVyZr, and -CrFeMnTiVZrz (0 <= u, v, w, x, y, z <= 2) alloys that are designated as C14 Laves-CruFevMnwTixVyZrz alloys are investigated in this study via results of pressure-composition-isotherms (PCIs) and hydrogen absorption kinetics of the alloys. XRD patterns show that alloy structure remains as C14 Laves after hydrogen absorption suggesting that the pulverization effect is less and this benefits cycle lives of alloy. Study of change in lattice parameters before and after absorption and desorption of hydrogen, i.e., the change in volume, illustrates the pulverization effect. Maximal hydrogen absorption in atomic percent is closely related to the hydride formation enthalpy shown in a (H-atom/M-atom)-Delta H-hydride curve. A composition trace map for hydrogen absorption, which benefits alloy design, is also shown in this study. (C) 2017 Elsevier B.V. All rights reserved.
