Abstract. The paper presents a part of the performed researches to synthesise new types of nanostructured composite materials with controlled distribution of the phases and multifunctional applications. Two innovative directions are squared up to: high temperature auto propagation synthesis of NiAlMe_x (where Me = Fe or Co; x = 5 or 10) inter-metallic compounds and synthesis of metal-ceramic nanostructured composites by a soft solution process (SSP). Nanostructured powders with core (NiAlMe_x inter-metallic compounds)-shell (alumina) distribution were obtained and characterised by chemical quantitative analysis, X ray diffraction, thermal analysis and scanning electron microscopy.
