Abstract:

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 achieve cost reductions over the current fabricated parts as a result of single-piece construction and near net shape processing.
