Kerstin Cuhls,Knut Blind,Hariolf Gruppe of beryllium in nuclear reactors and in jet and rocket propulsion systems. Since that time quite extensive use has been made of beryllium as a structural material in less corrosive environments. It has been used quite extensively for gyro systems, mirror and reentry vehicle structures, and aircraf

Tobias Popović,Michael Bossert,Uta BronnerExtrusion* is the most important technique for the production of simple or complex long shapes of beryllium metal. Historically, extrusion was the earliest fabrication method for sound beryllium shapes, and for a long time it remained the only method of producing a structural material with appreciable ductility.

Design Considerations,nd illumination of any other design considerations and material characteristics that greatly influence the selection of beryllium for structural applications. The function of this chapter is to define these considerations, identify the present status of beryllium design technology, and direct attent
