The intensity of cracking is reflected in the change of the specific powder surface during heating, and it depends on the phase formation in the barrier layer and its physicochemical properties. The real oxidation rate of disperse metals is higher than the diffusion rate in oxides, which indicates the determining role of cracking in the interaction mechanism Доп.точки доступа: Shevchenko, V.
