摘要
The microstructure of ZrFe2-based alloys were modified by alloying with the Mn, Ti, and V, aiming to obtain proper hydriding/dehydriding plateau features for the high-pressure application. The multi-component ZrFe2-based alloys show a wide tunable range in the plateau pressure via the interaction of Ti, Mn, and V. Further, the V addition plays the best role to improve the hysteresis in absorption-desorption isotherms, while the proper addition amount Ti helps to realize a low plateau slope as well as a high plateau pressure. Among the investigated alloys, Zr1.05Fe1.6Mn0.4 shows a relatively high dehydriding pressure of 20.58 atm at 298 K, while Zr1.05Fel.7Mn0.2V0.1 with C15 structure shows the lowest hysteresis. Overall, too much of Ti and Mn would promote the transformation of the C15 to C14 structure with large hysteresis and low plateau pressure. (C) 2020 Hydrogen Energy Publications LLC.
