The Mechanical Response of Nanoporous Gold and Silver Foams with Varying Composition and Surface Segregation
Source abstract
Abstract
Abstract The mechanical response of an Au-Ag nanoporous foam is studied via molecular dynamics simulations, while segregation effects are captured by a Monte-Carlo simulation scheme. The addition of silver to nanoporous Au structures increases the strength of the foams. Dislocation evolution in alloyed and pure elemental structures is analyzed. We find that the yielding behavior is dependent on surface compositions and the corresponding capillary forces, while elastic behavior is dependent on bulk composition. Trends in the yield response of this material as a function of size and surface composition are effectively predicted with a model that accounts for surface effects.
