Recent experiments provide evidence for density variations along shear bands (SB) in metallic glasses with a length scale of a few hundreds nanometers. Via molecular dynamics simulations of a generic binary glass model, here we show that this is stro

We present evidence of plastic avalanches in the so-called elastic regime of a glassy three dimensional Cu50Zr50 system. By means of extensive molecular Dynamics simulations we investigate this mechanical response of this system, subjected to tensile

Unifying interatomic potential, g(r), elasticity, viscosity, and fragility of metallic glasses: analytical model, simulations, and experiments

Autor: Alessio Zaccone, Konrad Samwer, A.E. Lagogianni, Zach Evenson, Johannes Krausser

An analytical framework is proposed to describe the elasticity, viscosity and fragility of metallic glasses in relation to their atomic-level structure and the effective interatomic interaction. The bottom-up approach starts with forming an effective

Publikováno v: Journal of Alloys and Compounds. 483:658-661

We present Molecular Dynamics Simulations results on the micro-structural characteristics of the CuxZr100 − x metallic glasses. In all stoichiometries studied, we found that the Cu-centered small icosahedral clusters (ICO) are a basic structured ob
