ABSTRACT

The phase composition and structure of initial powders and the products of oxidation of aluminum alloys with calcium and barium containing 0.88 and 0.26 at.% of dopants, respectively, have been studied for the first time by the diffraction method with the use of synchrotron radiation during programmed heating in air up to 1273 K at a rate of 10 K/min. It was established that as a result of the heterogeneity of the phase composition of the oxidation products and the structural changes in the oxide shell on the particle surface, aluminum oxide loses its high protective properties and metal oxidation is activated.
