| Περίληψη: | Title screen The study investigates the microstructure, phase composition, and hydrogen absorption properties of (TiVCr)94.8Me5.2(Me = Ni, Co, Zr) alloys to evaluate the influence of doping elements on hydrogen storage performance. Phase and microstructural analyses reveal the formation of multiphase systems, with distinct secondary phases depending on the additive. The research emphasizes the role of empirical parameters such as valence electron concentration (VEC), average electronegativity difference (EVD), and lattice parameter, rather than the conventional Ti/Cr = 0.75 ratio, in determining hydrogen storage properties. Results indicate that hydrogenation behavior correlates more strongly with EVD and lattice parameter than with VEC. Among the tested alloys, (TiVCr)94.8Zr5.2 exhibited the highest hydrogen capacity (1.79 wt %), along with superior kinetics and activation characteristics. The study also examines phase stability after hydrogen sorption/desorption cycles, noting transformations in secondary phases and their impact on performance. These findings suggest that optimizing hydrogen storage materials requires a holistic approach, balancing VEC, EVD, and lattice parameters, rather than adhering strictly to empirical compositional ratios. The insights gained can guide future alloy design for improved hydrogen storage efficiency under practical conditions Текстовый файл AM_Agreement |
