Metalworking III: Forging
The metal beryllium and the forging process have unique and intrinsic characteristics that would be expected to complement each other to provide specialized benefits for advanced technical applications. in view of this, government aerospace agencies and industry sponsored continuous programs throughout the 1960s for evaluating the effects of thermal—mechanical processing on beryllium. The text of this chapter is based primarily on beryllium forging work conducted during that decade. Forged beryllium was used for several aerospace applications. based primarily on higher yield strength, higher elongation, and improved material utilization. The lack of a broader range of demonstrated benefits, primarily cost reduction, prevented expansion of forged beryllium product to a wider variety of applications. While material savings for an expensive material such as beryllium should justify shaping via forging, the methods and precautions used and the relatively low production yield could not readily support its use for the needs of the time.
