Abstract: This paper presents the results of detonation and explosion characteristics for ammonium nitrate, aluminium, and aluminium-magnesium alloy powder mixtures. The following parameters were determined: detonation velocities, blast waves overpressure and their specific impulses. The emission of radiation was recorded, and the history of temperature of the detonation products cloud was established. It was shown that addition of aluminium-magnesium alloy powder increases blast waves’ characteristics. Moreover, it increases the time of the afterburning reaction after detonation and increases the temperature of detonation products.

Keywords: ammonium nitrate; aluminium-magnesium alloy powder; detonation velocity; modified ammonal; blast waves’ characteristics; temperature of the detonation products cloud (search for similar items in EconPapers)
