【 摘 要 】

Hydrogen storage and microstructure the TiCrV0.9, TiCrV0.9Zr0.2and TiCrV0.7Zr0.4alloys were investigated. The alloys were melted in arc furnace, the structure was analysed by X- ray diffraction and hydrogen absorption times were analysed by Sievert's type apparatus. The results showed that the addition of Zr replacing the V decreases in the absorption capacity passing of 3.8%wt to 2.0%wt in contrast the speed of hydrogen absorption increases considerably.
