英文摘要A comparative study of high-entropy metallic glasses and their reference counterparts was conducted via mechanical relaxation behavior and high-temperature deformation. We show that the high-entropy metallic glasses possess a relatively more homogeneous structure, which generates smaller activation volumes and sluggish free volume evolution during high-temperature deformation. A spectrum analysis that allows to delineate the deformation details of high-entropy metallic glasses were constructed. The core finding sheds important light on the structural heterogeneity and sluggish dynamics and provides an essential piece for understanding the deformation mechanism of high-entropy metallic glasses.
