    摘要: A method of producing a cobalt-based tubular product includes forming a cobalt or cobalt alloy tubular workpiece having at least about 30% by weight of fcc phase and subjecting the workpiece to at least about a 20% wall reduction at a temperature below a recrystallization temperature of the workpiece using a metal forming process. The metal forming process may include radial forging, rotary swaging, pilgering and/or flowforming. A gun barrel includes a tubular component made of a cobalt-based superalloy material. The component has at least about 25% by weight of hcp phase with basal planes radially oriented perpendicular to an inner diameter of the component.

    摘要: A method of producing autofrettage in a tubular component provides a tubular workpiece having an inner diameter and an outer diameter and provides at least two rollers having a displacement from one another in an axial direction with respect to the workpiece. The method places the workpiece on a mandrel such that the inner diameter is adjacent to the mandrel. The method also compresses the outer diameter of the workpiece with the rollers at a temperature below a recrystallization temperature of the workpiece using a combination of axial and radial forces so that the mandrel contacts the inner diameter and imparts a compressive hoop stress to the inner diameter of the workpiece.

    摘要: Gun barrels and similar tubular devices for repeatedly guiding fired projectiles are fabricated from superalloys, titanium metals, tantalum metals, and similar metal materials by a flowforming process. Combinations of these metals are also flowformed to produce gun barrels and projectile-guiding tubes. In addition, inner liners for such barrels and tubes are made with these metals and flowforming processes. These barrels and tubular devices can withstand high temperatures and corrosive environments. The flowforming process is efficient and produces strong, yet thin and/or light weight, gun barrels and similar tubular devices.

    摘要: A method of producing a seamless, tubular product includes centrifugally casting a corrosion resistant alloy into a tubular workpiece having an inner diameter and an outer diameter. The method then removes material from the inner diameter of the workpiece and subjects the workpiece to at least about a 25% wall reduction at a temperature below a recrystallization temperature of the workpiece using a metal forming process. The metal forming process includes radial forging, rolling, pilgering, and/or flowforming.
