Abstract
The reactivity of the mixture Mo-10 % B is investigated, along with the effect of the parameters of mechanical activation on heat evolution, specific surface, structure of powders, activation energy of combustion process, heat evolution rate, temperature and rate of combustion. It is shown that activation in the optimal regimes increases the reactivity of low-exothermal mixture Mo-10 % B. Using the technology of force compaction, a multilayer composite target for magnetron sputtering was obtained. It was established that the density and hardness of the synthesized material increase in the case if preliminary mechanical activation is applied.
