Il'in, L. Proskurovskaya] Conclusions: The UDP of aluminum, obtained by the electroexplosive technology, are structurally metastable which manifests itself in their reduced density. Such a state is characterized by the storage of energy which is equivalent to heating the particles of UDP by tens of degrees. When UDP of aluminum are heated in air at high rates, it leads to considerable spontaneous heating (to 2200°C) and the appearance of a considerable amount of bound nitrogen (up to 30% AlN) in the products. The degree of oxidation of UDP attains more than 60% at less than 660°C of the external heater. Relaxation processes in heating of UDP of aluminum lower the temperature of the onset of oxidation. With increasing stored energy ΔE the temperature of the onset of oxidation drops, and between the rate and ΔE a direct correlation was not discovered. It seems that the rate depends substantially on other parameters (sintering intensity, composition and state of the oxide layer). Plenum Publishing Corporation, 1991 Il'in A.
