Abstract: Thermokinetic data on the oxidation of ASD-4 powder modified by impregnation with V$_2$O$_5$ gel were obtained by thermogravimetry and differential scanning calorimetry under heating in air to 1250$^{\circ}$C at a rate of 10 deg/min. The phase formation process directly during oxidation of the modified ASD-4 was studied by powder x-ray diffraction method using a synchrotron radiation source. A mechanism for the effect of V$_2$O$_5$ on the oxidation of ASD-4 is proposed on the basis of literature data and analysis of the results of the studies performed.

Keywords: powdered aluminum, vanadium-containing hydrogels, activation of oxidation, completeness of oxidation, in-situ study of structural conversion.
