In the work the effect of structural changes, occurring in multilayer Al/Ni foils during their ageing (at temperature of 250 oC), on the rate of spreading of SHS reaction front is studied. It is shown that the rate of SHS front during the foil ageing is decreased, and its dependence on time of aging has a non-monotonous nature, It was found that the value of period of alternation of layers components and structure of interlayers, formed at the interface between the layers of Al and Ni, has a significant effect on intensity of reducing the rate of spreading the SHS reaction front in ageing of multilayer foils. Ref. 19, Figures 6.
Key words: electron beam deposition; reaction multilayer foils; Al/Ni; SHS reaction; phase transformations
