An analytical model of the consolidation process of NiAl matrix-coated Al2O3 fibers (MCFs) during diffusion bonding is presented. Several densification mechanisms are considered to quantify the diffusion bonding kinetics. A simple void geometry and its evolution during hot pressing are addressed. Also primary creep is accounted for in the model, and it is demonstrated that primary creep contributes the most important consolidation mechanism during hot pressing. A comparison of experimental results and model predictions based on these microstructural mechanisms shows good agreement. The model lends itself for a general prediction of the consolidation process of matrix-coated ceramic fiber-reinforced metallic and intermetallic matrix composites.
