【 摘 要 】

The present study describes the synthesis characterization and hydrogen storage behavior of Ti41.5+XZr41.5-XNi17(x=0, 3.5, 11.5 and 13.5) nano quasicrystalline ribbons synthesized through rapid solidification technique. The nano quasicrystalline ribbons of alloys have been synthesized at Cu-wheel speed of 45 m/sec. The investigation also describes the effect of different compositions of Ti and Zr on the structure, microstructure and their correlation with hydrogen storage characteristics of as quenched nano quasicrystalline ribbons. It has been found that the hydrogen storage capacity of these ribbons increases with increasing the content of Ti in i-phase ribbons.
