С. 86-88Abstract: In this work, we considered the results of experimental studies on the combustion of a NiB-Ti powder mixture in an SHS reactor. It was found that with an increase in the mass content of titanium powder from 36.5 wt. % up to 56.5 wt. % in the initial NiB-Ti mixture, the combustion rate decreases from 9 mm / s to 5 mm / s, while the combustion temperature also decreases from 1550 ° C to 1400 ° C. It is shown that at the stage of preparation of the initial charge there is a fundamental possibility of obtaining powders of cermet composite materials (Ni-Ti) -TiB2 with a controlled phase composition and structure.
