RADIAL EXTRUSION OF TURBOJET DISCS
Abstract
Full-scale AMS 6342 steel compressor disks can be precision forged by radial extrusion techniques with the following benefits: (1) Web thicknesses to blueprint with virtually no carburization and tolerance; (2) press tonnages at approximately 1/2 those needed for conventional forging methods; and (3) metal volume overages of 29.6% instead of 230% obtained in conventional forging techniques. Full-scale AMS 4928 titanium compressor disks can be semi-precision forged by radial extrusion techniques at press tonnages of approximately 57% of those required for conventional forging methods. Precision forging AMS 4928 titanium compressor disks by radial extrusion techniques to blueprint web thicknesses is hindered by surface contamination and poor surface finish. (Author)
