Advanced Methods of Hot Forming Cross-Rolled Beryllium Sheet 680650

The established parameters for hot forming cross-rolled beryllium sheet have been expanded to incorporate advanced configurated structural components and production details during the last year. Tooling, forming equipment, and forming techniques have been improved to fulfill these requirements.
Experimental conical sections, drawn cups and hat sections have been formed. Production circular frame caps, stiffeners, splice plates, and curved channels have also been produced. Hot-forming tooling has been utilized in furnaces, hot-forming presses and hydraulic presses to form these details. The forming of the production parts has produced over-all manufacturing cost data reflecting material costs, tool design and fabrication costs and cost of forming.
Conclusions and recommendations for future work have been made concerning the effects of forming parameters on material properties and for improvements in tool designs, equipment designs and forming techniques.
