Self-propaging high-temperature synthesis of mechanically activated mixtures in $\mathrm{Co}$–$\mathrm{Ti}$–$\mathrm{Al}$

Combustion of mechanically activated mixtures in $2\mathrm{Co}$–$\mathrm{Ti}$–$\mathrm{Al}$ and $\mathrm{Co}$–$2\mathrm{Ti}$–$\mathrm{Al}$ is investigated, and alloys based on them are synthesized in self-propagating high-temperature synthesis. Microstructural, X-ray, and differential-thermal studies are performed. A Heusler phase $\mathrm{Co}_2\mathrm{Ti}\mathrm{Al}$-based alloy is obtained for the first time by means of mechanical activation. Conditions for the mechanical activation of a reacting powder mixture for the formation of a single-phase material is experimentally selected.
