“…При этом в процессе приготовления многослойных фольг или под воздействием различного рода термических обработок на границе между слоями образуются диффузионные прослойки вследствие реакционного взаимодействия компонентов, что неизбежно будет сказываться на их реакционных свойствах. Одним из наиболее существенных факторов, оказывающих влияние на реакционную способность фольги, является толщина образующихся диффузионных прослоек [11].…”

В работе изучено влияние структурных изменений, возникающих в многослойных Al/Ni фольгах при их старении (при температуре 250 о С), на скорость распространения фронта реакции СВС. Показано, что скорость фронта СВС при старении фольги уменьшается, а ее зависимость от времени старения имеет немонотонный характер. Установлено, что существенную роль на интенсивность снижения скорости распространения фронта реакции СВС при старении многослойных фольг оказывают величина периода чередования слоев компонентов и структура прослоек, образующихся на границе между слоями Al и Ni. библиогр. 19, ил. 6.

“…Condition for producing foil with maximum HGI can be also determined, if we use equation (5) to calculate HGI for foil with the smallest multilayer period (foil 1), and plot this value on the graph of W dependence on multilayer period λ (see Figure 10). One can see that the thus obtained experimental point can be correlated with one of W dependencies on multilayer period λ, earlier calculated for MF with different interlayer thicknesses.…”

Characteristics of the process of self-propagating high-temperature synthesis (SHS) to foil with multilayer structure based on elements, capable of formation of intermetallic compounds, are determined by many thermodynamic and structural parameters. This significantly complicates the possibility of prediction of the features of SHS reaction running in them at the change of the foil structure and chemical composition. In the study, analysis of effectiveness of these parameters influence on SHS reaction front temperature and velocity in multilayer foil was performed within the framework of a phenomenological model. It is shown that the velocity of SHS front propagation and heat generation intensity nonmonotonically depend on structural parameters. In the case of Ni/Al multilayer foil, structural parameters were established, for which maximum values of heat generation intensity are reached in the foil in SHS process, and the method for their determination was proposed. 8 Ref., 1 Table, 11 Figures.
