Compressibility of AR 2206 Gun Propellant Grains.

Abstract

Grains of AR2206 gun propellant have been compressed individually and in bulk at rates from 5 to 50 mm/min at 20 C. At these rates, extensive plastic deformation of the grains occurs, with no signs of brittle shattering of the grains. At 5 mm/min, individual grains can deform up to 25% before fracture occurs, and in bulk, the grains can be compressed by 52% without showing any significant fracture. Small cracks at geometrical stress points have been observed. (Author)
