Experimental results of an investigation of the mechanochemical synthesis of composite powder of the TiB\(_2\)ľMoSi\(_2\) system in a wide concentration range with a MoSi\(_2\) content of 20-60 mass.% are presented. As shown, it is impossible to obtain a two-phase TiB\(_2\)ľMoSi\(_2\) composite powder during mechanosynthesis of multicomponent (Ti + B + Mo + Si) reaction mixtures in the concentration range 40-80 mass.% TiB\(_2\), and the final product is a mixture of the following phases: the solid solution (Ti,╠ţ)B\(_2\), Mo\(_3\)Si, Mo\(_5\)Si3, MoB\(_2\). For the (Ti + B + MoSi\(_2\)) reaction mixture, a two-phase composite powder (TiB\(_2\) and MoSi\(_2\)) forms within 30 min at the ball-to-powder mass ratio 10:1. The results of mathematical modelling of the distribution of contacts between powder particles of the reaction mixtures agree well with the experimental results of mechanosynthesis.

Keywords: mechanosynthesis, composite powders, titanium boride, molybdenum disilicide, contacts, mathematical modelling
