Aldas, KMat, MD2019-08-012019-08-0120050924-0136https://dx.doi.org/10.1016/j.jmatprotec.2004.06.021https://hdl.handle.net/11480/5603Particle distribution in particulate metal matrix composites was investigated experimentally and theoretically. SIC reinforced Pb 20%Sn alloy mechanically was stirred and cast into a cylindrical mold by an inert gas pressure. Particle distribution in the cast is determined at several locations by sectioning and microscopic investigation techniques. The particle fraction is found to decrease along the axis of the mold. The regions close to the boundary wall are determined as the possible clustering areas. A mathematical model is developed to characterize flow of mixture of molten metal alloy and ceramic particles. The distribution of particles is estimated from the trajectories of representative particles with the Lagrangian point of view. The numerical results are reasonably suited with experimental data.
