Insight Into

Microstructures in the reaction interface between molten Al and dense mullite have been studied by transmission electron microscopy to provide insight into mechanisms for forming ceramic–metal composites by reactive metal penetration. The reactions, which have the overall stoichiometry 3Al6Si2O13 + (8 + x)Al → 13Al2O3 + xAl + 6Si, were carried out at temperatures of 900, 1100, and 1200 °C for 5 and 60 min and 1400 °C for 15 min. Observed phases generally were those given in the above reaction; their proportions and interfacial microstructures, however, were strongly dependent on the reaction temperature. Using previously measured reaction kinetics data, the observed temperature dependence of the interfacial microstructure has been modeled as three sequential steps, each of which is rate limiting in a different temperature range.

The Impact

Co-continuous ceramic composites were fabricated with commercially available SiC porous foams as the ceramic phase and aluminium 6021 alloy as the metallic phase using reactive metal penetration (RMP) process. Microstructure studies, compression test, microhardness test and tests to determine the impact strength were performed on the co-continuous composite. The fabricated composite was lighter and it was found to possess properties comparable to aluminium 6021 alloy.
