Abstract
A method of preliminary mechanical activation is used to implement the combustion of a Ti + Ni mixture, which does not burn at room temperature. The dependences of the burning rate, maximal temperature of combustion, and elongation of samples on the mechanical activation time of the Ti + Ni powder mixture are described for the first time. Moreover, the microstructure and phase composition of activated mixtures of their combustion products are studied. The mechanical activation time (9 min) during which the burning rate of the mixture and the content of the main phase (TiNi intermetallide) are maximal in the combustion products is experimentally determined. In these conditions, the combustion propagates within a narrow zone—the maximal temperature corresponds to that in the combustion front.
