Mechanochemical Modification of Nickel Aluminide with Aluminum Oxide

The products of mechanically stimulated interaction of NiO with Al were studied by X-ray diffraction and IR spectroscopy. Composites Ni/α-Al 2 O 3 , NiAl/α-Al 2 O 3 , Ni 2 Al 3 /α-Al 2 O 3 can be fabricated by varying the ratio of initial components under the selected conditions of mechanical activation. The approach under consideration, based on a mechanically stimulated reaction, makes it possible to significantly simplify the previously proposed method of mechanically activated self-propagating high-temperature synthesis and produce nanostructured composites.
