PERFORATING CHARGE CASE

摘要

A perforating charge case is made by a process that includes cold forming a material into a shape for the perforating charge case. The cold forming produces additional recrystallization nucleation sites in the material. After the col d forming, the material may be annealed to decrease sizes of grains of the material to improve a ductility of the material to increase fragment sizes of the perforating charge case wh en an explosive that is placed inside the perforating charge case detonates
