Abstract: Ti–Al multilayer foils were produced magnetron vacuum deposition. The microstructure period varied in the range of 5–110 nm, the number of layers was 150–4700, and the total thickness of a multilayer foil reached 15–20 $\mu$m. The gasless combustion of the foils was studied. Steady-state and pulsating combustion regimes were revealed; combustion temperatures were determined for both regimes. It was shown that the most probable mechanism of the self-propagating reaction is the diffusion of Al in $\beta$-Ti at a temperature close to the temperature of the $\alpha\to\beta$ transition.

Keywords: gasless combustion, multilayer foils, nanostructures, intermetallic compounds.
