Recent Advances in Forging Beryllium for Aerospace Applications 660634
The deformation processing of beryllium is discussed with respect to mechanical properties, economics and manufacturing considerations. Production techniques using closed impression die forging, extrusion and ring rolling have been established for manufacture of wrought beryllium shapes which include discs, hemispheres, cylinders, shafts and rings. The metallurgical aspects of the response of beryllium to thermo–mechanical treatments are presented. Current activity includes development of procedures for manufacture of large conical shapes with height–to–diameter ratios greater than one.
