Importance of dislocations in ultrasound-assisted sintering of silver nanoparticles

For acoustic softening of solid materials, it has been suggested that the enhancement of dislocation motion by ultrasonic irradiation plays some role. In order to study the role of dislocations in ultrasound-assisted sintering of silver nanoparticles, numerical simulations are performed using a model developed from the solid-state sintering model by Kraft and Riedel coupled with the models of evolution of mobile and immobile dislocations and...
