Abstract
The behavior of a growing dendrite when approaching a particle in the melt determines the distribution of the particles in the finished metal-matrix composites (MMCs). A sharp interface level-set based numerical method is employed to study dendrite-particle interactions. The simulation of the interaction between particles and dendrites grown from pure material shows that for a particle to melt thermal conductivity ratio

(typical for MMCs), the dendrite does not approach the particle close enough to activate particle pushing. Instead, the dendrite chooses to go around the particle and eventually the particle is engulfed by sidebranches. Thus the entrapment mode is the likely outcome. The simulation of interaction of a particle with a dendrite grown from a binary alloy is also carried out.
