This paper describes an expanded mechanism of metal combustion that emphasizes reactions and phase changes occurring within the burning metal in addition to those occurring on and above the metal surface. Selected recent experimental work showing the importance of these internal processes in metal combustion is surveyed. Gas dissolution within the burning metal, ensuing phase changes, and their effects on combustion are discussed. Metal-gas phase diagrams are used to interpret the experimentally observed metal combustion behavior. Some concepts aimed at designing improved metal-based high energy density materials and controlling metals flammability are briefly addressed.
