Query: Correlation between Internal States and Strength in Bulk Metallic Glass   The internal states or local structures of bulk metallic glass (BMGs) can be
well reflected from the changes of density, structural relaxation as well as
the elastic constants. With the increasing free volume (FV) content, more local
atomic clusters are capable of simultaneous plastic shear at different sites in
the metallic glasses, inducing large plasticity. In this work, we report a
close correlation between the internal states and strength in a BMG and
discover that the yield strength can be changed by varying of the casting
current, revealing that the yielding strength of BMGs is not only intrinsically
associated with the glass transition, but also with the internal states, such
as free volume and elastic properties. Such results may have some implications
for understanding the correlations between the internal states and mechanical
properties of BMGs.
