Contribution

It demonstrates shear-induced ordering in a metallic glass model through detailed simulation analysis, highlighting nucleation processes at low temperatures.

Findings

Shear flow causes crystallization in a metallic glass model.

Order formation depends on strain rate and temperature.

Transition rates between states are characterized.

Abstract

We report results of non-equilibrium molecular dynamics simulations of a one-component glassy system under the influence of a shear flow, with the aim of investigating shear induced ordering of this system. In spite of the very low temperature, the system transforms into a strained crystalline state through well defined nucleation events. Various characteristics of the observed ordering at different strain rates and temperatures are discussed. We also define and discuss the transition rates.
