Combustion of pressed specimens of heterogeneous systems subjected to a constant axial mechanical load

The growth dynamics of the height of burning pressed specimens with the specimen ends subjected to a compressive force of constant magnitude is studied using the heterogeneous Ti+C+20% TiC system as an example. It is found that in the examined range of compressive forces 0.1–2 kg/cm$^2$, the growth of the height of the burning specimens with time obeys a linear law; under a compressive force of $\approx$0.1 kg/cm$^2$, the specimen height increases by $\approx$100%, and under a force of $\approx$2 kg/cm$^2$, it increases by about 25%. The method used to measure the growth dynamics of the specimen height during combustion proved a useful tool for the experimental determination of both the burning time of the specimens and the delay in the transfer of combustion through an obstacle.
