TL;DR: In this article, a mechanistic model for grain boundary migration is proposed, based on the formation and migration of line defects (disconnection) within the GB, and the results capture all of these observed temperature dependencies and are shown to be in quantitative agreement with each other and direct simulations of GB migration for a set of specific grain boundaries.

TL;DR: In this article, the local parameters are introduced to describe the local atomic structure of amorphous metals and define the structural defects which facilitate the explanation of various properties, including the volume change by annealing.

TL;DR: In this paper, the authors present a theoretical analysis of the effects of thickness on surface segregation in thin films, which predicts surface composition as a function of the heat of segregation, temperature and film thickness.

TL;DR: In this article, a combined molecular dynamics and finite element model and simulation of contact and adhesion between a rough sphere and a flat surface has been developed using the results of molecular dynamics simulations, obtained using an embedded atom potential, of a nanoscale Ru-Ru asperity contact.

TL;DR: In this article, a micromechanical continuum model for the unique tensile behavior of single-crystalline face-centered-cubic metal (Cu, Ni, and Au) nanowires is presented.
