Influence of preliminary mechanical activation conditions on thermal explosion characteristics of the titanium–nickel powder system

Resumo

The influence of conditions of preliminary mechanical activation on the structure and temperature characteristics of self-propagating high-temperature synthesis of a Ti–Ni powder mixture in the thermal explosion mode is investigated. The lamellar agglomerate structure and the granulometric composition of the powder mixture are studied. Features of the powder mixture formation with mechanical activation, which affect the characteristics of subsequent thermal explosion, are determined.
