Summary:Title screen
In this work, the effect of in-vacuum low-temperature auto-ignition of a W–Cu2O nanopowders mixture obtained by natural oxidation of W–Cu composite nanopowders is demonstrated. The powder is obtained via electrical explosion of wire technique and consists of bimetallic particles instead of Cu and W mixture. The evolution of the phase composition has been studied using in situ X-ray diffraction technology during heating. The structural investigation shows that particles have a core-shell structure, increasing a contact surface between reactants. The ongoing reactions are described, and studies of the structure of powders and combustion products are given. Combustion occurs in the solid-phase temperature range, which is confirmed by the thermal imaging data.
