Synthesis and Hydrogenation of the Ti_45−xV_xZr₃₈Ni₁₇ (5 ≤ x ≤ 40) Mechanically Alloyed Materials

Abstract

The mechanically alloyed amorphous alloys of the Ti45Zr38Ni17 composition are known for their ability to form a quasicrystalline state after thermal treatment. It is also known that the amorphous and quasicrystal alloys belonging to the Ti45Zr38Ni17 family are able to store hydrogen and yield gravimetric densities above 2 wt.%. In this contribution, we report the results of research on the Ti45Zr38Ni17 system with vanadium doped instead of titanium. We found that the amorphous samples with moderate doping (x 45−xVxZr38Ni17 with moderate V doping.
