Method and apparatus for forming a thixoforged copper base alloy cartridge casing |
摘要 |
A process and apparatus for forming a thin-walled, elongated member having superior strength properties from an age hardenable copper base alloy is described herein. A slug or billet of a slurry cast, age hardenable copper base alloy is formed into a semi-solid slurry having about 10% to about 30% of the alloy in a liquid phase. The semi-solid slurry is then thixoforged to form the thin-walled, elongated member. Thereafter, the member is age hardened to provide a product having desired strength properties. The process and apparatus of the instant invention may be utilized to form cartridge casings.
