Reaction thermodynamics and wetting studies were employed to evaluate boron carbide-aluminum cermets. Wetting phenomenon and interfacial reactions are characterized using ''macroscale'' and ''microscale'' techniques. ''Macroscale'' evaluation involved aluminum sessile drop studies on boron carbide substrates. ''Microscale'' evaluation involved the fabrication of actual cermet microstructures and their characterization through SEM, x-ray diffraction, metallography, and electron microprobe. Contact-angle measurements and interfacial-reaction products are reported. 14 refs., 5 figs., 2 tabs.
