Resumen:
The interaction of iron paticles with an advancing solid-liquid interface has been examined in lead and lead alloys. In the case of pure lead solidified with a planar interface, the particle distribution in the solid and quenched liquid was uniform, indicating particles were not rejected at the interace. For interfaces with a cellular and dendritic structure the particles were concentrated in the cell walls and interdendritic regions. This concentration is accounted for on the basis of the particle velocity and convective flow in the melt during the particle interface interaction. A water model was examined which simulated the metal system, using nylon spheres for particles and a lucite cellular surface for the interface. The results confirmed that particles concentrated at intercellular regions as a result of the particle velocity and fluid flow.
