What is aluminum combustion mode on thermal explosion can occurs ?
4 answers
Aluminum combustion in the mode of thermal explosion (TE) can occur under various conditions and mechanisms, as elucidated by multiple studies. The general theory of thermal explosion, developed by N. N. Semenov, indicates that combustion synthesis (CS) systems, including those involving aluminum, exhibit a non-monotonic dependence of reaction rate on temperature, where phenomena such as melting of the precursor can sharply increase the reaction rate. This is particularly relevant in the formation of aluminum-based composites and alloys, where the thermal explosion mode of combustion synthesis method triggers reactions between aluminum and other materials, as seen in the creation of Cu-Al alloys. Mechanochemical treatment (MCT) has been shown to influence thermal explosion in aluminum powder blends, enhancing the maximum temperature of thermal explosion and stabilizing the combustion process. This suggests that the physical manipulation of aluminum particles can affect their reactivity and the conditions under which thermal explosion occurs. The size of aluminum particles plays a significant role in their ignition and combustion behavior. Studies on nano- and micro-sized aluminum particles have shown that ignition temperature varies significantly with particle size, influenced by the mode of heat transfer to the particle. This indicates that thermal explosion in aluminum systems can be critically dependent on the physical characteristics of the aluminum itself. Furthermore, the presence of a constant magnetic field has been found to influence the combustion of aluminum nanopowder under thermal explosion conditions, favoring the formation of specific compounds. This highlights the complex interplay of external conditions and material properties in determining the combustion mode of aluminum. In situ fabrication of aluminum metal matrix composites via thermal explosion reveals that aluminum not only acts as a diluent but also participates in the reaction, affecting both the process and the final products. This participation is crucial in the thermal explosion synthesis of materials involving aluminum. The study of aluminum and copper powder mixtures heated to self-ignition temperatures further elucidates the phase transformations and kinetics of heat release during thermal explosion, providing insight into the macrokinetic stages of aluminum combustion. Lastly, experiments with molten aluminum have shown that thermal explosion can occur with varying degrees of intensity, influenced by the temperature of the aluminum melt and the conditions of the experiment. This underscores the variability of thermal explosion phenomena in aluminum systems under different thermal conditions. In summary, aluminum combustion in the mode of thermal explosion can occur through various mechanisms, influenced by factors such as the physical treatment of aluminum, particle size, external magnetic fields, and the specific conditions of the reaction environment.
