摘要: Methods of manufacturing metal, metal-matrix, metal-metal-matrix composite weapon barrels offer barrels with improved thermal performance and rigidity with no, minimal or negative weight increase. A barrel may include a barrel core surrounded by a lightweight, thermally conductive sleeve made from metal, metal-matrix composite (MMC) materials, also referred to as metal-matrix material. The barrel core and barrel sleeve may include aligning features to prevent separation and movement of the sleeve along the core. The disclosed methods provide for material combinations and part designs that prevent separation of their parts over the life of the weapon barrel and allow the barrel to perform at high cadence over the whole temperature range the barrel is used.

摘要: A weapon barrel includes an inner core and an outer sleeve. The inner core has a first end, a second end, a bore extending from the first end to the second end, and an external surface extending from the first end to the second end. The inner core includes a material selected from the group consisting of a ferrous alloy, a non-ferrous alloy, a ceramic, a bonded ceramic, and a cemented carbide. The outer sleeve has a first end, a second end, an internal surface extending from the first end to the second end, and an external surface extending from the first end to the second end. The outer sleeve is disposed around and permanently joined to the inner core. The outer sleeve includes a material selected from the group consisting of a metal-matrix composite and a beryllium alloy, the outer sleeve material being located at and between the internal surface and the external surface of the outer sleeve.
