“…Meanwhile, the heat release increased as the modulation periods of the RMFs increased. This was because the increasing area of the contact interface (between metallic oxide and Al films) made the oxygen of the metallic oxide layer diffuse into the Al layer spontaneously and react with the Al atoms, resulting in a misuse of energy [2, 16, 24, 29–31]. For the RMFs of TiO 2 /Al, the first exothermic peak corresponded to the solid-solid reaction between TiO 2 and Al before Al melting, and the second peak represented the liquid-solid reaction between the melted Al and TiO 2 .…”

Three types of reactive multilayer films (RMFs) were integrated to the energetic flyer plates (EFPs) by depositing TiO 2 , MnO 2 , and CuO onto aluminum films with different modulation periods using magnetron sputtering technology in this study. The effects of the laser ignition property and laser reflectivity on the RMFs and the thermal behavior of the RMFs were analyzed and compared with those of a single-layer Al film. A high-speed video, photonic Doppler velocimetry (PDV), and a thermal analysis were utilized to characterize the flame morphology, EFP velocity, and chemical thermal behavior, respectively. The surface reflectivities of the TiO 2 /Al, MnO 2 /Al, and CuO/Al layers were measured using laser reflectivity spectrometers. The results showed that RMFs with smaller modulation periods exhibited excellent laser ignition performances, and EFP with MnO 2 /Al had the best performance. These RMFs achieved flame durations of 120–220 μs, maximum flame areas of 7.523–11.476 mm 2 , and reaction areas of 0.153–0.434 mm 2 (laser-induced with 32.20 J/cm 2 ). Flyer velocities of 3972–5522 m/s were obtained in the EFPs by changing the material and modulation period of the RMFs. Furthermore, the rate of the chemical reaction and laser energy utilization were also enhanced by reducing the modulation period and using different material. This behavior was consistent with a one-dimensional nanosecond-laser-induced plasma model. The RMFs of MnO 2 /Al exhibited the highest level of energy release and promoted laser energy utilization, which could better improve the performance of laser ignition for practical application.

“…The DTA/DSC based methods are the most widely used for gasless SHS systems, with multiple studies into intermetallics, specifically the Ni/Al [35][36][37][38][39][40][41][42][43], Ti/Al [44][45][46], Co/Al [47], Al/Ru [48], Nb/Al [49], and Mg/Al [50] systems, in addition to other binary solid-solid compositions, i.e., the Si/C [51], Mo/Si [52], Zr/B [53], Fe/Se [54]. More complicated ternary systems were also investigated [54][55][56][57][58][59][60][61].…”

“…For 4:1 foils, they found that the formation of NiAl 3 occurred, followed by Ni 2 Al 3 , with activation energies of 142 and 106 kJ/mol, respectively [37]. [42]. Without the lubricant, the reaction proceeded in a single step with activation energy of 470 kJ/mol, this difference was attributed to the oxide layer between the reactants [42].…”

In this chapter, we present an overview of experimental techniques utilized and kinetic data collected for exothermic self-sustained noncatalytic heterogeneous reactions. The data focuses on five primary experimental techniques: electrothermal explosion, differential thermal analysis, electrothermography, combustion velocity/temperature analyses, and several advanced in situ diagnostics, including time-resolved X-ray diffraction.
