BERYLLIUM FORGING PROGRAM
Abstract
Unclad Be was forged successfully in closed dies on an experimental production basis using expendable die components of hot carbon steel which reduce tensile stresses while deforming plastically. Reproducibility was achieved through development of tooling and forging sequences applicable to the specific shapes required. The final forging configuration for 2 parts was produced repetitively while production runs of the initial, extrusion forging operation were also completed for 2 other parts. Preliminary tryouts are being conducted on the 2 remaining parts which have thin wall configurations. A successful method for ring rolling Be was not developed although results were sufficiently encouraging to warrant further investigation. A heat treatment investigation on separate heats of Be indicated that, within the limits of the treatments and the specific forgings investigated, a temperature of 1525 F for 16 hr followed by air cooling, imparts the most desirable combination of properties.
