Redistribution of second phase particles in solidifying alloy melts—entrapment and microsegregation within dendritic networks

Particles disperesed in a melt get redistributed during solidifacation due to buoyant motion and interactactions between the particles and the solidification front. In alloy melts the distortion of the concentration field by the particle leads to entrapment of the particle within the dendritic netwo...
