Detonation Performance of Al{sub}3Mg{sub}4 Enriched Explosives and Afterburning of the Detonation Products

摘要

The research on an effect of an alloy of aluminium and magnesium (Al{sub}3Mg{sub}4) contents on detonation characteristics of RDX-based compositions was carried out. Measurements of detonation velocity were performed. Parameters of blast waves produced by charges of the investigated explosives detonating in an open space were measured by the use of piezoelectric gauges. Quasi-static pressure measurements were conducted in a steel chamber of 0.15 m3 volume filled with air. Moreover, the heat of detonation was measured with a calorimetric set in a 5.6 dm3 bomb filled with argon. A degree of combustion of the metallic addition is also discussed.
