Abstract

The electrochemical capacity, hydrogen absorbed/desorbed activation properties of alloy Zr(Mn_0.1V_0.3Ni_0.6)₂ were improved after Ti substitution for the Zr. The microstructure of Zr_1xTi_x (Mn_0.1V_0.3Ni_0.6)₂ (x = 0, 0.5) alloys was analyzed by x-ray diffraction (XRD), transmission electron microscopy (TEM), and energy dispersive spectrum (EDS) analysis. A systematic structural analysis shows that there are two phases in the Ti-substituted alloy of Zr_0.5Ti_0.5(Mn_0.1V_0.3Ni_0.6)₂: C14 Laves phase and Ti-containing “premartensite” R phase of Ti_0.8Zr_0.2Ni. The improvement of electrochemical properties of alloy Zr(Mn_0.1V_0.3Ni_0.6)₂ after Ti substitution can be attributed to the Ti substitution for Zr sites in C14 Laves phase, the formation of Ti_0.8Zr_0.2Ni R-phase, and disappearance of Zr–Ni binaries.
