“…The interest in improved metal fuels is stimulated by development of solid propellants (De Luca et al, 2004Habu, 2008;Price, 1984), explosives (Frost et al, 2007;Gogulya et al, 2008;Jones and Zerilli, 1993;Zarei and Frost, 2011), and pyrotechnics (Nacu, 2011;Rajendran et al, 2000;Smit et al, 1997). While aluminum is by far the most widely used metal additive in energetic formulations, it was reported that advanced combustion performance can be achieved when aluminum-magnesium alloys are used (Breiter et al, 1971(Breiter et al, , 1983Popov et al, 1973;Poyarkov, 1967;Roberts et al, 1993;Yuasa and Takeno, 1982;Zenin et al, 2011).…”

Burn times and temperatures were measured optically for a set of mechanically alloyed Al·Mg powders injected into a laminar and a turbulent air-acetylene flame. Magnesium concentrations varied from 10 to 53 mole%; particle sizes were in the range of 1-50 µm. Emission from the burning particles at 700 nm, 800 nm, and 900 nm was captured using three filtered photomultiplier tubes. The burn times were correlated with particle sizes using measured statistical distributions for both times and sizes. The measured trends for burn times, t, as a function of particle size, d, for all alloys were approximated by a t = a·d n law, where the exponent n varied from 0.6 to 1. Shorter burn times were measured in more turbulent flows; respectively, the values of pre-exponent, a, decreased and exponent, n, increased slightly with an increased level of turbulence. An increase in Mg concentration led to longer burn times for the alloy particles for all flame conditions. For all compositions, alloy particles burned longer than similarly sized Al particles except for the alloy with the smallest concentration of Mg, Al 0.9 Mg 0.1 , for which particles less than ∼4 µm burned faster than similarly sized Al. This effect was observed for laminar and turbulent flames. The optically measured temperatures were lower for Al 0.47 Mg 0.53 alloy (∼2400 K) compared to ∼2700-2800 K obtained for other alloys. Turbulent mixing resulted in a slight increase in the measured temperature.

“…Due to their larger surface area-to-volume ratio, it is theorized that the addition of nanometer-sized metal particles may strengthen detonation waves due to more rapid oxidation and the subsequent thermal transport to the explosive combustion gases. However, experimental results measuring the performance of metalized explosives have been inconclusive [7,24,16,15,19,25]. Some experiments indicate that mixtures containing metal nanoparticles reduce detonation speeds compared to standard micron-sized particles, while others suggest that detonation speeds can increase under certain conditions [47].…”
