The propagation-mode, compacted-powder combustion synthesis of intermetallics is analyzed through a combined particle-level/specimen-level treatment. The specimen-level treatment is based on the local volumeaveraged conservation equations for species and energy. The particle-level treatment considers a uniform temperature, the formation of products through a diffusioncontrolled heterogeneous reaction, and allows for melting of the product assuming a distinct interface between the phases. An experiment is performed with the aluminumtitanium system with a 3-1 stoichiometry. The temperature distribution and the combustion front speed are measured and the extent of conversion and uniformity of the final product are determined using electron microscopy.
