Characterization of Zr-Cu Base Metallic Glasses by means of Hydrogen Internal Friction Peak

The hydrogen internal friction peak in Zr50-metallic glasses (Zr50Cu50 ,Z r 50Cu40Al10 and Zr50Cu35Al10Ni5) was studied. The hydrogen internal friction peak was shifted exponentially to lower temperatures with increasing hydrogen concentration similarly to other Zr-Cu base metallic glasses reported in the literature. The peak height increased in proportion to the square-root of hydrogen concentration. These results were discussed in the view point of the hydrogen induced structural relaxation in these metallic glasses. [doi:10.2320/matertrans.MJ200727]
