Title
Near-net-shape Processing of Metal-ceramic Composites by Reactive Metal Penetration
Abstract
Metal-ceramic composites were made to near-net shape by reacting phase-pure mullite and mullite-glass preforms with molten Al using a reactive metal penetration process. Conversion of the two ceramic preforms to Al2O3/Al composites was accompanied by a 0.32% volume expansion and a 1.42% volume shrinkage, respectively. Molar volume and density calculations made assuming a net-shape reaction estimate ∼17 and ∼27 vol% Al to be present in the two composites after reaction. Results from quantitative stereology measurements used to quantify the concentration of metal in the reactively formed composites validate the calculations.
