FIELD: measuring.
SUBSTANCE: invention relates to the field of nanotechnology of materials and can be applied in researching the properties of multi-layered reaction materials with a self-propagating high-temperature synthesis (SHS) effect, in particular, for determining the combustion temperature of such materials. Proposed is a method for determining the combustion temperature of multi-layered reaction nanofilms based on an application of electrical methods. The combustion temperature is determined by the change in the electrical resistance of a strip of the multi-layered reaction nanofilm prior to and after the process of self-propagating high-temperature synthesis, and the combustion temperature tshs is calculated by the formula tshs = to+(Rt-Rx)/Rx∙α, wherein to is the temperature prior to the SHS, Rx is the resistance of the strip of the multi-layered reaction nanofilm prior to the SHS, Rt is the resistance of the strip of the multi-layered reaction nanofilm after the end of the SHS, α is the temperature resistance coefficient of the multi-layered reaction nanofilm.
EFFECT: increased informational value and rapidity of determining the combustion temperature of multi-layered reaction nanofilms.
