Influences of Multilayer Graphene and Boron Decoration on the Structure and Combustion Heat of Al(3)Mg(2) Alloy

To improve the engine-driven performance of propellants, high-energy alloys such as Al and Mg are usually adopted as annexing agents. However, there is still room for improvement in the potential full utilization of alloy energy. In this study, we investigated how to improve combustion efficiency by...

description To improve the engine-driven performance of propellants, high-energy alloys such as Al and Mg are usually adopted as annexing agents. However, there is still room for improvement in the potential full utilization of alloy energy. In this study, we investigated how to improve combustion efficiency by decorating Al(3)Mg(2) alloy with multilayer graphene and amorphous boron. Scanning electron microscopy and Raman tests showed that decorating with multilayer graphene and amorphous boron promoted the dispersion of Al(3)Mg(2) alloy. The results showed that decorating with 1% boron and 2% multilayer graphene improved the combustion heat of Al(3)Mg(2) alloy to 32.8 and 30.5 MJ/kg, respectively. The coexistence of two phases improved the combustion efficiency of the matrix Al(3)Mg(2) alloy.
