Abstract :
It has been found that metal nanopowders produced by wire electrical explosion have stored energy, which is higher than the standard heat of melting. Continuing studies on stored energy the influence of electrons flow (accelerator ELU-4) on iron and nickel nanopowders has been investigated in the paper. It was found that the thermal effect of oxidation for iron nanopowders after exposure increased in comparison to the thermal effect of unirradiated nanopowders 4 times, and for nickel nanopowders 1.4 times. The model of metal nanoparticle with stored energy has been proposed in the article.
