Abstract
The size-dependent deformation behavior of Zr65Cu17.5Ni10Al7.5 bulk metallic glass in supercooled liquid state was investigated through finite element simulations combined with the free volume constitutive relation, based on both uniaxial compression and tension. Taking into consideration the extrinsic effect (i.e. interfacial friction) in compression, the simulated results revealed a relatively more homogeneous flow and free volume distribution in the Zr-based bulk metallic glass with larger sample size. While under uniaxial tension without any interfacial friction but with the same temperature, stain and strain rate as what were used in compressive experiments, the simulated effective stress, strain and free volume concentration are almost identical at all sample sizes, denoting an intrinsic size-independent deformation behavior.
