Abstract
It has been shown that Ti-Al-N ternary compounds, belonging to MAX phases (ceramic materials that can be processed as metals) can be produced by combustion of a granular powder of T65Yu35 (TiAl) alloy in nitrogen flow at a pressure close to atmospheric pressure. Combustion is accompanied by transfer of part of the aluminum through the gas phase. The propagation velocity of the combustion zone and the maximum temperature increase with increasing flow rate.
