Abstract

Abstract

To obtain low detonation velocity explosive, commercial attenuant was blended into the emulsion explosive. The detonation velocity of compound explosive changes from 2 550 m/s to 1 450 m/s. Through analyzing the result of mechanical properties test and microstructure test of the Al/316L composite tubes which were fabricated by explosive welding of compound explosives, the appropriate detonation velocity (1 950~2 150 m/s) for the explosive welding of composite tube is obtained, and the combination quality of the composite tubes meet the subsequent processing requirement. The shape of the interface waveform is between line and wave. Interfacial wave also has poor rule of periodic variation. The reasons are that detonation velocity is important to the process, the explosion product does not scatter in the direction of tube diameter and the time that detonation products inside the tube affect to the flyer tube is longer than the flyer plate in the explosive welding process.
