N2 - The technique of synthesis of Ni-16mass%Al open cell type porous intermetallic materials that can be treated in inert or regenerative atmospheres at temperature up to 1600 K without changing their functional properties has been developed. Materials with Ni3Al-NiAl phase composition, porosity of 42%, sizes of transport pores up to 10 μm, sizes of core elements equal to 40 μm, and specific surface of open porosity of 90 mm-1 have been produced. It is demonstrated that after complete oxidation of the given materials, the NiO-NiAl2O4 composite is formed, whose reduction in hydrogen flux results in the formation of Ni-NiAl2O4 cermet; the shape of the porous material in the course of oxidation/reduction does not change.
