Segregation in Porous NiTi Made by SHS in Flow Reactor

“…a b During SHS of porous titanium nickelide, glowing of different intensity was repeatedly observed in the local regions of the reaction zone. These observations suggest thermal heterogeneity of the reaction zone and this corresponds to the experimental results obtained in the study of different SHS systems reported by other authors [8][9][10]. They showed that the heat released during the reaction in SHS is distributed as self-similar traveling waves, and the reaction front has a fractal structure.…”

Application of self-propagating high-temperature synthesis and mechanical activation for obtaining nanocomposites

“…As it follows from the review [24], such products cannot be obtained in composite systems by means of conventional SHS.…”

“…In all examined multicomponent SHS systems, the size of ceramic-phase particles substantially decreases as the content of the inert matrix in the reactive mixture increases. In the conventional SHS, however, it is hardly possible to obtain ceramicphase particles smaller than 1 µm [24].…”

Critical regimes of volume ignition of mechanically activated Ti-C-Ni mixtures

“…The particle size of the ceramic phase is found to decrease substantially with increasing content of the inert matrix in the reactive mixture in all examined multispecies SHS systems. Nevertheless, the conventional SHS methods usually cannot ensure obtaining ceramic particles smaller than 1 µm [7,8].…”
