- Abstract
In the process of small-caliber ammunition production, the quality of the setting of the deep drawing technology of CuZn30 brass and its subsequent recrystallization is essential. The quality of the setting of this technological process is also very important for the final quality of the whole ammunition, as the cartridge case, or even the projectile, is produced by the technology of deep drawing. In deep drawing technology in cartridge case manufacturing, when CuZn30 brass already reaches the value required for recrystallization, the brass structure changes the grain size of the structure. And at the same time, makes it difficult to achieve a uniform grain size in the entire cartridge case cross-section after recrystallization or after some steps of the technological process.
