Popis:	We present the results of the recent experiments with two species of Ni/Al reactive multilayer nanofoils (RNMFs) supporting the self-propagating high-temperature synthesis (SHS) reaction. SEM method was used to evaluate their general structure and quantitative chemical composition before and after reaction. Phase composition was determined from XRD spectra. Special attention was paid to the stability of phase composition over relatively long time intervals after SHS reaction – order of the hours and days. In some cases, XRD spectra showed notable evolution of crystalline structure, which can have significant impact on practical application of SHS, for instance, in soldering technologies. To our knowledge, similar effect has been previously observed only for SHS-reactive powder mixtures.
