Abstract: Combustion during self-propagating high-temperature synthesis of $\mathrm{Ti}+1.7\mathrm{B}$ reaction tapes obtained by rolling from a powder mixture is experimentally investigated. Dependences between the combustion wave propagation velocity in the reaction tapes and the applied pressure are revealed. It is shown that the burning rate of the tapes weakly depends on the compression pressure within $0.001$–$4$ MPa. At a compression pressure above $0.5$ MPa, unreacted regions appear during the combustion of the tapes. The limiting pressure at which the combustion stops is determined as $12$ MPa.

Keywords: self-propagating high-temperature synthesis (SHS), combustion, reaction tapes, rolling, titanium, boron, pressure.
