It is known that the room-temperature plastic deformation of bulk metallic glasses is
compromised by strain softening and shear localization, resulting in near-zero tensile …

A structural signature of liquid fragility

NA Mauro, M Blodgett, ML Johnson, AJ Vogt… - Nature …, 2014 - nature.com
Virtually all liquids can be maintained for some time in a supercooled state, that is, at
temperatures below their equilibrium melting temperatures, before eventually crystallizing. If …

Correlation between the elastic modulus and the intrinsic plastic behavior of metallic glasses: The roles of atomic configuration and alloy composition

YQ Cheng, AJ Cao, E Ma - Acta Materialia, 2009 - Elsevier
Recent reports suggest that Poisson's ratio (ν), or the related ratio of shear modulus G to
bulk modulus B, indicates the potential of metallic glasses (MGs) to sustain plastic strain …
