Settling of silicon carbide particles in cast metal matrix composites

摘要: Abstract The success of metal matrix composites as potential materials for the manufacture engineering components depends on closer control their microstructure during processing. One important factors influencing is settling particles liquid processing these composites. In this paper SiC in cast aluminium alloy composite was studied function particle size, weight fraction and melt temperature isothermal holding solidification experiments. Isothermal A356 reinforced with 20 wt.% silicon carbide showed that occurs at significantly slower rates than predicted by theoretical models. results also appears to have a slight effect behaviour. Experiments mixing revealed low temperatures volume does not affect rate but increases tend settle when present lower fractions.
