Abstract

MA SHS was used for preparation of oxide / intermetallics nanocomposites. Mechanochemical reduction of Fe2O3 was investigated in conditions of high dilution by iron and aluminium. It shows that excess of Al content significantly alters the process. Mechanical activation of mixture 60.9 wt.% Fe + 26.6 wt.% Al + 12.5 wt.% Fe2O3 leads to formation of nanocomposite Al2O3/Fe/Al, and following SHS creates nanocomposites Al2O3/FeAl.
