ABSTRACT:
An explosive shell case of the kind in which fragments are produced by bursting of the case material into a number of small particles. The case material comprises a completely dense, non-compressible material which is made with embrittling zones (4) which when the shell bursts gives fragments of a predetermined shape. The case is preferably manufactured powder-metallurgically, the embrittling zones then being formed by filling at predetermined intervals with powder with the embrittling component. The case is then pressed under high all-round pressure and high temperature into a dense, compact jacket and is imparted its final properties through heat treatment.
