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)
