The possibility of using an axial force probe to detect self-oscillating co
mbustion of samples which yield solid reaction products and some amount of
gas is demonstrated. Densified samples of Ti + C + 20% TiC containing disti
lled water in compression pores were used in the experiments. The parameter
s of the fluctuations in the pressure of the gaseous phase in the reaction
front are determined for these samples as they burn in a self-oscillating r
egime.
