DOI: 10.1016/j.intermet.2021.107234
Abstract: Abstract Fe-based bulk metallic glasses (BMGs) usually exhibit brittle behavior and unconspicuous β-relaxation in their dynamic mechanical spectroscopy. We report a distinct β-relaxation behavior in FeNi-based BMGs with excellent plasticity. The origin of pronounced β-relaxation… read more here.
