The work presents the results of numerical modelling of thermal fields in zone of joining of aluminum plates through intermediate layers in process of local heating of joining zone by flat heater, contacting with one of the plates. The layers consisting of solder alloy, multilayer reactive foil or layers of both types were considered as an intermediate layer. The calculation was carried out considering thermal-physical characteristics of the plate material, intermediate layer and heater, consisting of the multilayer reaction foils, in which a reaction of self-propagating high-temperature synthesis is accompanied by intensive heat emission. There were studied the conditions of local heating of the aluminum plates necessary for obtaining the permanent joints in the process of their soldering or welding through intermediate layer. 14 Ref., 1 Tabl., 11 Fig.
