Influence of Zr Addition on the Microstructure and Hydrogenation Kinetics of Ti_50-xV₂₅Cr₂₅Zr_x (x = 0, 5, 7, and 9) Alloys.

ABSTRACT: Due to the poor activation performance and kinetics of Ti₅₀V₂₅Cr₂₅ alloys, the element Zr was added to improve the phase structure of the alloy and achieve a high-performance hydrogen storage alloy. The Ti_50-xV₂₅Cr₂₅Zr_x (x = 0, 5, 7, and 9) system alloys were prepared by arc melting. The alloys were analyzed using an X-ray diffractometer (XRD), scanning electron microscope (SEM), and differential scanning calorimeter (DSC). The hydrogen storage capabilities of the alloys were also obtained by the Sievert volumetric method. The results indicated that the alloy with Zr added had a combination of the C15 Laves phase and the BCC phase, whereas the Zr-free alloy had a BCC single phase. The partial replacement of Zr wit
