This work shows that the structure-phase composition of the surface of porous titanium nickelide manufactured using a self-propagating high-temperature synthesis (SHS) under the condition of layerwise combustion considerably changes as a function of the initial synthesis temperature. At low temperature of the powder mixture burning in the mode of pulsed combustion, a large amount of slag is formed on the external surface of the reaction layer, while at high temperature in the mode of continuous combustion the surface is covered with a nanostructured layer of sulfides, silicides, and oxides. The concentrational and structural composition of the master phase undergoing a thermoelastic phase transformation is similar for both synthesis regimes.
