Effect of intermixing on self-propagating exothermic reactions in Al/Ni nanolaminate foils
TL;DR: In this article, the authors measured the effect of intermixing thickness on the reaction velocities in multilayered Al/Ni nanolaminate foils and found that increasing the intermixed region from 2.4 to 18.3 nm reduced the reaction velocity for all of the foils.

Modeling and characterizing the propagation velocity of exothermic reactions in multilayer foils
TL;DR: In this paper, an analytical model dealing with the premixing is presented and compared with experimental results for Al/Ni and Al/(Ni:Cu) multilayers, and it is concluded that to use these foils in commercial and engineering applications, the method of fabrication and the phase changes occurring during the reaction must be controlled to give the desired characteristics.

Al/Ni formation reactions: characterization of the metastable Al9Ni2 phase and analysis of its formation
TL;DR: In this article, the metastable phase Al9Ni2 was investigated in order to characterize the thermodynamics and kinetics of its formation, and it was observed as the first phase to form in a series of sputterdeposited Al/Ni multilayer foils, but it did not form in foils with a very small bilayer period.

TL;DR: In this paper, the authors studied the CuOx/Al exothermic reactions in multilayer foils to identify reaction paths and reaction kinetics and showed that the reduction of CuOx and the oxidation of Al proceeded via two separate exotherms.

Self-propagating formation reactions in Nb:Si multilayers
TL;DR: In this article, the authors investigate self-propagating formation reactions in Nb/Si multilayers and demonstrate that their reaction velocities decrease as the individual Nb and Si layers thicken.
