Abstract

Abstract: Most metallic glasses (MGs) exhibit weak evidence of slow β-relaxation in their dynamic mechanical spectroscopy. In contrast to other MGs, we find a series of Fe-based MGs with unusual distinct β-relaxation peaks in their relaxation spectra. The investigation on the β-relaxation behavior of Fe-based MGs suggest that the magnetic element Fe plays the critical role in the pronounced β-relaxation behaviors in the Fe-based metallic glasses, which could provide deep insight into the mechanism of β-relaxation dynamic mode in metallic glasses. Highlights: A series of Fe-based MGs show pronounced β-relaxation in their dynamic spectrum. The magnetic element has a critical role in the pronounced β-relaxation behaviors. The Fe-based metallic glasses with pronounced β-relaxation could provide deep insight into the mechanism of β-relaxation dynamic mode in metallic glasses.
