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 NiAlMex
(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 (NiAlMex inter-metallic
compounds)-shell (alumina) distribution were obtained and characterised by
chemical quantitative analysis, X
ray diffraction, thermal analysis and scanning electron microscopy.
