Shape-formation in the processes of self-propagating high-temperature synthesis of foams

Self-propagating high-temperature synthesis of cylindrical specimens of foa m cermet with a relatively large length (l/D much greater than 1) is perfor med. A Ti + 0.6C mixture containing foaming agent Na2B2O7 . 10H(2)O was use d. The initial compacts were enclosed in burning paper shells, which during self-propagating high-temperature synthesis made it possible to produce st raight rods of foam ceramics, distinguished by an even surface. The depende nce of the relative elongation of the specimens on the shell thickness was established. The possibility of controlling the shape of the foam SHS produ ct by varying the slope of the combustion-front plane to the specimen axis was considered.
