Metalworking IV: Forming

  • Jack J. Blakeslee

Abstract

Beryllium may be readily formed into many useful objects by using conventional sheet-metal-forming techniques, and is therefore quite valuable as an engineering material. In the early 1960s beryllium forming was limited to stretch or creep forming, or three-point bending around very generous radii. With the advent of a reliable process for making ingot-source beryllium sheet in the mid-1960s,(1) the formability of beryllium was improved and deep drawing could be used as an efficient process for forming hemispheres and boxlike structures. Also the formability of powder-source block material has been improved to such an extent that it has been used as a production process.(2) For clarity the term ingot source refers to beryllium sheet or plate produced by directly rolling and/or forging a cast product. The term powder source refers to all beryllium consolidated from beryllium powder regardless of attritioning method and includes materials that have been subsequently rolled and/or forged.
