DEVELOPMENT OF TECHNIQUES FOR PRODUCING BERYLLIUM STRUCTURAL SHAPES
Abstract
Solid shapes (rou ds and squares) of Be were prove readily producible through simple roll reduction of previously extruded sh pes GL S, CHANN L , AND EES CA BE ORMED THROUGH THE B DING OF S EET METAL OF T E DESIRED THICKNESS TO THE DESIRED GEOMETRY. F OR FORMI G T !% O !$) F, n 0.06 -i .- hick heet required 3T to 4T internal forming radius if roll forming was used whereas a 7T radius was necessary for mechanical press brake forming. For 0.188-in.t ick heet a radiu of 3T to 4T was required for roll forming, and mechanical press brake forming required a 4 1/2T radius for s tisfactory ben s in this temperature range. A composite billet process was developed for production of tee shaped sections not producible by th m thods used for t o h r sh pes. Pot n ial exists in his method for e production of complex shap to hig r rength l vels than those originally specified. Introductory experiments demo strated the ability to achieve ov r 1 0 00 psi ul imate ensile str ngt a d 0,000 psi tensile yield strength with 5% elongation. (Author)
