Abstract:

The influence of a permanent magnetic field (0.78 T) on the energy release rates for a series of eight transition metal energetic complexes was investigated using magnetic-field–enhanced laser-induced air shock from energetic materials (B-LASEM). Differences in the microsecond-timescale energy release based on laser-induced shock velocities, high-temperature chemistry using high-resolution emission spectroscopy, post-plasma combustion chemistry, and self-sustained combustion reactions on the millisecond timescale were compared with and without the magnetic field. The resulting trends suggest a complex relationship between the properties of the energetic material and the energy release rates. While the energy release rates on the microsecond (and millisecond) timescale could be shifted either earlier or later under the magnetic field based on the properties of the sample, the largest observed magnetic field effects were on the intensity and duration of the combustion reactions at later timescales.
