Abstract Investigation of detonation parameters, blast wave characteristics and quasi‐static pressures (QSPs) for the mixtures of nitromethane and particles of an aluminium and magnesium (Al 3 Mg 4 ) alloy was carried out. The mixtures of gelled nitromethane containing 15–60 wt.‐% AlMg alloy were tested. Detonation velocity and Gurney energy were determined. Parameters of blast waves produced by charges of the investigated explosives were measured. QSP measurements were conducted in a steel chamber of 0.15 m 3 volume filled with air. Thermochemical and gasdynamical calculations were also performed. The degree of combustion of the metallic addition with the gaseous products during detonation and expansion is discussed.
