Abstract: The effect of the phase composition of an aluminum-based alloy powder containing 1.3% calcium and the products of its interaction with air on the kinetics and mechanism of oxidation was first shown by x-ray diffraction using synchrotron radiation. It was found that the high surface and chemical activity of calcium led to an increase of more than a factor of two in the completeness of the process in the temperature range of 1300–1550 K upon heating at 10 K/min.

Keywords: aluminum powder, metal fuel, in situ study of structural transformation, alloying, oxidation activity.
