The processes associated with self-propagating high-temperature synthesis (SHS) in the Ti−Al−C powder system are studied, with hexamethylenetetramine amine (С6H12N4), polytetrafluoroethylene, and amorphous carbon (aC) used as carbon precursors. The key parameters of SHS and way the it unfolds are shown to be determined by the carbon precursor used and a technique employed for preparing initial powder samples. With the indicated carbon precursors, we are able to prepare nanostructured composite materials containing titanium carbide and the Ti2AlC MAX phase, while the Ti3AlC2 MAX phase is formed under specific conditions in the Ti−Al−С6H12N4 and Ti−Al−aC powder systems.
