“…Accordingly, the heat of reaction could be further increased by conducting the milling process in an argon atmosphere. In milling experiments by Lee et al [23], which were likewise conducted in an air atmosphere, values for the heat of reaction between 906 J/g and 1150 J/g were obtained on the basis of DSC analyses. However, this comparison must be considered critically due to the different milling equipment used as well as the distinct method of analysis.…”

“…As a result, tailored reactive particles can be produced for thermal joining applications. Similar to Hadjiafxenti et al [11], Gunduz et al [22], and Lee et al [23], the thermal material properties are determined using differential scanning calorimetry (DSC) in this work. In order to correlate the DSC measurements with the microstructures of reactive particles, an additional optical evaluation is required.…”

Reactive particles consisting of nickel and aluminum represent an adaptable heat source for joining applications, since each individual particle is capable of undergoing a self-sustaining exothermic reaction. Of particular interest are particles with intrinsic lamellar microstructures, as they provide large contact areas between the reactants nickel and aluminum. In this work, the exothermic reaction as well as the microstructure of such lamellar reactive particles produced by high energy planetary ball milling were investigated. Based on statistically designed experiments regarding the milling parameters, the heat of reaction was examined by means of differential scanning calorimetry (DSC). A statistical model was derived from the results to predict the heat of reaction as a function of the milling parameters used. This model can be applied to adjust the heat of reaction of the reactive particles depending on the thermal properties of the joining partners. The fabricated microstructures were evaluated by means of scanning electron microscopy (SEM). Through the development of a dedicated SEM image evaluation algorithm, a computational quantification of the contact area between nickel and aluminum was enabled for the first time. A weak correlation between the contact area and the heat of reaction could be demonstrated. It is assumed that the quantification of the contact areas can be further improved by a higher number of SEM images per sample. The findings obtained provide an essential contribution to enable reactive particles as a tailored heat source for joining applications.

“…Valuable information on phase formation was obtained with in situ time-resolved XRD and synchrotron radiation diffraction studies [206][207][208], as well as time-resolved TEM [209,210]. Influence of various external forces and fields including HEBM [211][212][213], microwaves heating [214], applied electric fields and different gravity conditions [215,216], on the process of synthesis, structure, and properties of the synthesised intermetallics have also been studied. Some features of the ignition and combustion mechanisms in aluminium-based reactive materials were considered in a recent review [217].…”

Self-propagating high-temperature synthesis (SHS) or combustion synthesis (CS) is a rapidly developing research area. SHS materials are being used in various fields, including mechanical and chemical engineering, medical and bioscience, aerospace and nuclear industries. The goal of the present paper is to provide a comprehensive state-of-the-art review and to analyse a critical mass of knowledge in the field of SHS materials and coatings. We also briefly discuss the history and scientific foundations of SHS along with an overview of the technological aspects for synthesis of different materials, including powders, ceramics, metal-ceramics, intermetallides, and composite materials. Application of CS in the field of surface engineering is also discussed focusing on two main routes for applying SHS to coating deposition: (i) single-step formation of the desired coatings and (ii) use of SHSderived powders, targets or electrodes in the coating deposition processes.
