✦ Synopsis

The dynamics of phase formation in the combustion wave of the titanium-nitrogen, titanium-oxygen, and titanium-air systems have been investigated. The experiments were on an installation composed of a position detector and a standard x-ray apparatus. The combustion wave in the Ti-N 2 system has been found to propagate as a result of the formation of titanium nitride, which is the final product. The phase formation process in the Ti-O 2 system is caused by oxidation of titanium to titanium dioxide without formation of any intermediate oxide phases. In the Ti-air system the combustion front propagation is induced by the formation of the intermediate phase, titanium nitride, which converts to the final product, titanium dioxide, via two oxynitride intermediates.
