Abstract

A composite material based on Ti–Al–N was obtained from titanium and aluminum powders by self-propagating high-temperature synthesis in the wave combustion mode in a nitrogen atmosphere. The study of this system was of interest for the production metal-ceramic materials based on the MAX phase of Ti2AlN (phases Mn + 1AXn, where n = 1, 2, 3, …; M is a transition d-metal; A is a p-element; X is N). The resulting composite was studied by X-ray diffraction, scanning electron microscopy, and energy dispersive X-ray microanalysis. It was shown that the MAX phase of Ti2AlN, nitrides TiN and AlN, and intermetallic compounds TiхAlу were formed in the sample. A detailed analysis of the morphological distribution of the constituent phases was performed, based on which the mechanism of formation of the phase composition of the composite under conditions of layer-by-layer filtration combustion of the material was discussed.
