Abstract 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 Ti 50 Ni 44 Fe 6 alloy. This internal friction peak disappears in the de-hydrogenated Ti 50 Ni 44 Fe 6 alloy. It is proposed that the anelastic behavior of Ti 50 Ni 44 Fe 6 alloy results from the interaction between hydrogen and nanodomains.

Ti50Ni44Fe6合金弹性行为的起源

摘要 “应变玻璃”合金的弹性行为机制与“应变玻璃冻结”和松弛的前马氏体弹性并列。我们在此报告，氢是 Ti 50 Ni 44 Fe 6 合金中 160 K 附近与频率相关的内摩擦峰的基本成分。该内摩擦峰在脱氢的Ti 50 Ni 44 Fe 6 合金中消失。提出Ti 50 Ni 44 Fe 6 合金的非弹性行为是氢和纳米域之间相互作用的结果。
