Abstract

In order to improve the properties and to prepare Zr-Ti-V alloy, V was partially substituted with Ti in ZrV₂ alloy. The microstructure, the initial activation and dynamic performances of hydrogen absorption of the alloy are studied. It was found that the Zr-Ti-V alloy has a low activation temperature to absorb hydrogen fast and a good anti-powder capability due to the composite structure consisting of columnar crystals and small equiaxed crystals. The kinetic curves of hydrogen absorption exhibit dual-slope characteristics with a critical temperature T_c of 573 K to 673 K. When the temperature was below T_c, the hydrogen absorption rate is controlled by the phase transition rate, from large to small with time increasing; and when the temperature was above T_c, the hydrogen absorption rate turns from large to small with time increasing, controlled by the surface reaction process.
