The project described in this report demonstrates the feasibility of squeeze casting two specific munitions components: the 81mm M374 mortar body and a preform for the 155mm M483 projectile body. Squeeze casting is a hybrid of conventional casting and forging techniques which involves one-step conversion of molten metal into near net-shape components or preforms. Also termed 'liquid metal forging,' this process involves pouring molten metal into metallic dies in a hydraulic press and...

Technology was established for combining thermomechanical treatment (TMT) with internal shear forging in the manufacture of 2014 aluminum alloy subshells with integral internal ribs. These structures are currently fabricated from 2014-T6 sheet and plate stock by welding together the cylindrical outer skin of the subshell and a series of internal stiffening rings. The objective of the project was twofold: to enhance the properties and performance of these structures by means of TMT and to...

Large steel sections are used extensively as reinforcing structural members in the shipbuilding industry. T-sections, for example, often measure 30 in. x 1/2 in. in the web region and 10 in. x 1 in. in the flange region, and are over 40 ft long. These structural sections have to be twisted, with the toe of the web as the axis, to conform with the curving profile of the ship body. The twisting is generated primarily near each end of the section length, and is normally in the range of 1-2...
