中文摘要	The studies of the dynamical mechanical properties of a series of (CexLa1-x)(68)Al10Cu20Co2 (where 0 <= x <= 1) metallic glasses show that the behaviors beta relaxation are closely correlated with the properties of their corresponding supercooled liquids. Metallic glasses quenched from fragile liquids show pronounced beta relaxation humps whereas unobvious excess wings are associated with the metallic glasses quenched from strong liquids. Our result suggests he behaviors of beta relaxations in the metallic glasses are correlated with the fragility of their supercooled liquids. (c) 2011 Elsevier B.V. All rights reserved.
