N2 - Metal fuels are widely used in energetic materials to improve their energy release. Al[sbnd]Si alloy fuel is an aluminum-based alloy fuel, and its slow reaction rate limits its potential application in energy material systems. Herein, Al-Si-Mg AlSi9Mgx alloy fuel had been designed and successfully prepared by gas atomization to achieve excellent reactivity characteristics. The reaction characteristics of the fuel were systematically measured by thermal analysis (TG-DSC), bomb calorimeter, volumetric explosion vessel system and laser ignition measurement. Due to the addition of highly active magnesium, the activation energy of alloy fuel was reduced, and the combustion efficiency was increased to more than 99 %, and the ignition delay time was reduced by 6.7 ms and 33.6 ms respectively. Combustion of potassium perchlorate (KP) mixtures shows that AlSi9Mgx alloy fuels had a faster flame propagation rate, 22.814 mm/s and 42.543 mm/s. The superior reaction properties of AlSi9Mgx alloy fuel are due to the presence of internal solid solution Mg or low melting point alloy compound. This work and design provide a reliable method for optimizing the energy output of alloy fuels.
