Summary

Studies of the transformation kinetics and resulting microstructures of C materials processed at various temperatures are presented. C4 materials are produced through a displacement reaction between solid silica and molten aluminum. Evidence suggests that three distinct, temperature related processing regimes exist, each of which yields characteristic kinetic behavior and microstructures. Through the identification of the various phases and morphologies present in the microstructure, coupled with the observed kinetic behavior, a transformation mechanism for the evolution of the material is proposed.
