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

Abstract

The hydrogenation characteristics and embrittlement behavior of Ti50Zr((50-x))Cu-x alloys (x=25,33,40) are reported. The hydrogenation kinetics decreased with increasing Zr-content. Though the Ti5Zr25Cu25 alloy showed the slowest kinetics, it absorbed large amount of hydrogen (similar to 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.
