TiVCr alloys known for their potentially large
hydrogen uptake were formulated as (TiCr1.8)100-xVx in order to quantify the impact of the vanadium
concentration. Parallel to this series of pure ternaries, a second one was
synthesized with 4 mol.% of Zr7Ni10 addition. Structural
investigation and electrochemical charging with hydrogen revealed a fair
dependence of the hydrogen uptake and hydride stability on the vanadium
content, but conversely different due to the presence of the Zr-Ni additive.
HER overvoltage for (TiCr1.8)100-xVx versus the V
content.
