摘要：

The mechanism of anelastic behavior in "strain glass" alloy is juxtaposed between "strain glass freezing" and relaxational premartensitic anelasticity. We report here that hydrogen is an essential ingredient for the frequency-dependent internal friction peak around 160 K in Ti50Ni44Fe6 alloy. This internal friction peak disappears in the de-hydrogenated Ti50Ni44Fe6 alloy. It is proposed that the anelastic behavior of Ti50Ni44Fe6 alloy results from the interaction between hydrogen and nanodomains. (C) 2015 Acta Materialia Inc. Published by Elsevier Ltd.
