摘要：

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 mum. 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-->beta transition.
