چکیده انگلیسی
In order to clarify the hydrogen-induced structural relaxation (HISR) of hydrogenated bulk and marginal metallic glasses (BMG and MMG), the hydrogen concentration (CH) dependence of the peak temperature (Tp) and the peak height (Qpâ1) of the hydrogen internal friction peak (HIFP) in a-Zr55Cu30Al10Ni5 (numbers indicate at.%) (BMG), a-Zr54Cu30Al10Ni5Si1 (MMG) and a-Zr40Cu49Al10Si1 (MMG) were studied. It is found that the Tp versus CH data and the Qpâ1 versus CH data are well explained by the relationships of Tp = ÎTp exp(âCH/ÏH) + Tp,0 and Qpâ1âln(CH/ÏH), respectively, not only for all the present metallic glasses but also for various Zr-base BMG and MMG reported. The characteristic CH dependence of Tp and Qpâ1 was attributed to effects of the HISR. The detailed features of the CH dependence of Tp and Qpâ1 were discussed in the light of material parameters and HISR.
