Abstract
Experimental studies of combustion stability to a local excess of a component in a dispersed mixture of titanium and carbon powder are presented. The influence of the spreading of a melt of a fusible or liquid reaction product on the stability of the combustion transition through a solid and perforated carbon powder barrier is considered. The direction of melt movement with respect to the direction of front propagation has been studied. It is shown that the stability of the combustion transition through the barrier is determined by the thermal interaction between the combustion wave and the barrier and is not directly related to the convective heat transfer by the melt.
