Mechanical response of an Au-Ag nanoporous foam
Molecular dynamics simulations reveal the influence of solute segregation
2020/11/03 by K. Albe
Dislocation evolution in alloyed and pure nanoporous foams is studied by molecular-dynamics simulations. 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 modelthat accounts for surface effects.
