“…This is confirmed by other works [1,[10][11][12], where a differential scanning calorimeter DSC was used. Generally, the prevailed opinion is that irrespective of stoichiometry of the initial system, Al 3 Ti is the first compound created at the interface of the reacting materials.…”

“…However for many of these applications, the high theoretical combustion enthalpy of aluminum could not be practically achieved within the required time periods due to long metal ignition delays, particles agglomeration before ignition, slow burning rates and incomplete combustion [5][6]. Powders of metastable aluminum-based alloys have been proposed to address these problems in order to increase burning rates [6][7][8]. Interesting physicochemical properties would be obtained for alloy particles through chemical reordering and spatial redistribution of constitutional atoms [9].…”

This work investigated the oxidation, ignition and thermal reactivity of alloy nanoparticles of aluminum and copper (nAlCu) using simultaneous thermogravimetric analysis (TGA) and differential scanning calorimeter (DSC) method. The microstructure of the particles was characterized with scanning electron microscope (SEM) and transmission electron microscope (TEM), and the elemental composition of the particles before and after the oxidation was investigated with energy dispersive X-ray spectroscopy (EDS) and X-ray diffraction (XRD).The particles were heated from room temperature to 1200 o C under different heating rates from 2 to 30 K/min in the presence of air. The complete oxidation process of the nAlCu was characterized by two exothermic and two endothermic reactions, and the reaction paths up to 1200 o C were proposed. An early ignition of nAlCu, in the temperature around 565 o C, was found at heating rates ≥ 8 K/min. The eutectic melting temperature of nAlCu was identified at ~ 546 o C, which played a critical role in the early ignition. The comparison of the reactivity with that of pure Al nanoparticles showed that the nAlCu was more reactive through alloying.
