The influence of the component ratio, mechanical activation and preliminary compression of the samples on the burning rate and elongation of uncompressed samples during synthesis, on the phase composition and morphology of the combustion products in the (5Ti + 3Si) + (Ti + 2B) system was studied. The combustion front did not reach the lower end of the sample from the initial 5Ti + 3Si mixture. Preliminary compression of the sample, as well as mechanical activation of the 5Ti + 3Si mixture, or the addition of a Ti + 2B mixture allowed the sample to burn to completion. The burning rate and elongation of samples from (100 - x)(5Ti + 3Si) + x(Ti + 2B) mixtures increased after mechanical activation. A tendency towards a decrease in the burning rate with an increase in the 5Ti + 3Si content in the mixtures was recorded. The combustion rate of samples from mechanically activated mixtures increased after compression and remained virtually unchanged for the initial mixtures (except for the Ti + 2B mixture). For some initial mixtures, shrinkage of the product samples was observed after preliminary compression. The maximum combustion rate was measured for samples containing 20% of the 5Ti + 3Si mixture. The dependence of the elongation of samples from the initial (100 - x)(5Ti + 3Si) + x(Ti + 2B) mixtures on their composition exhibited extremes. The phase composition of the combustion products remained unchanged after compression of the samples and mechanical activation of the mixtures.
