Abstract

Various Ti-Mn-V based ternary alloys, known as AB2 type hydrogen storage alloys, were prepared and evaluated in order to clarify their crystal structures and hydrogen absorption/desorption properties. As a result, Mn-rich alloys with C14 laves structure were found to show a small hysteresis loop on absorbing/desorbing hydrogen. Furthermore, the effect of doping 4th and 5th element atoms on Ti-Mn-V based ternary alloys were evaluated. Then, Mn-rich Zr doped Ti-V-Mn alloys, like Ti30-xZrxV15Mn50, revealed most effective hydrogen storage capacity. Finally, we have found that a cooling process of melted alloys is important for synthesizing more homogeneous alloys, and successfully developed Ti25Zr10V15Mn50 with a rapid solidification process as one of the most effective hydrogen storage materials.
