Titanium carbide, because of its high modulus, high hardness and high melting temperature, is an attractive compound for use as a reinforcing phase in metallic matrices. The purpose of the present study is to investigate the process of microstructural evolution during laser igniting self‐propagating high‐temperature synthesis of Al/TiC composite to get a better understanding of the mechanism of the combustion synthesis. On the basis of these experimental results, a mechanism of the combustion synthesis was proposed, and a model corresponding to the mechanism was discussed.
