Abstract

Molecular-dynamics simulations have been used to study the consolidation of nanoparticles of aluminum. We have studied two- and three-particle sintering as it is influenced by temperature, particle size and crystallographic orientation. We have elucidated the dominant transport mechanisms by measuring the shear stresses that develop in the contact regions and the mobilities of the surface and core atoms during sintering. Our studies demonstrate that increasing the particles size slows down the sintering kinetics. The extent of interpenetration of the particles is independent of the particle size and is a function of the temperature of the particles.
