Abstract:

New and efficient metal-shaping procedures for the fabrication of 7. 62mm gun barrels were evaluated. The materials considered were Inconel 718, Vasco-Jet M-ACVM, and a cobalt-base alloy in powder form. Gun drilling, ECM stem drilling, hot piercing and extrusion, and filled-billet extrusion were evaluated for tube fabrication before subsequent precision rotary swaging of the rifling. Gun drilling of these alloys was the most economical tube fabrication procedure. The filled-billet technique is most amenable to consolidation-tube fabrication from powdered alloys. Precision rotary-swaging was evaluated for rifling the tubes and for determining the feasibility of combined rifling and chambering during swaging.
