Ti-based amorphous alloys and composites as potential candidate materials for energy applications

摘要

The hydrogenation characteristics and embrittlement behavior of Ti_(50)Zr_((50-X))Cu_x alloys (x=25,33,40) are reported. The hydrogenation kinetics decreased with increasing Zr-content. Though the Ti_(50)Zr_(25)Cu_(25) alloy showed the slowest kinetics, it absorbed large amount of hydrogen (～2.4 wt.%) and exhibited the best resistance against hydrogen embrittlement. The excellent characteristics of Ti-Zr-Cu alloys in hydrogen environment indicated that they are promising materials in future for energy applications.
