Beryllium sheet has been rolled from hot-extruded, hot-forged, and cold- compacted electrolytic beryllium powder. Room-temperature tensile tests have shown that maximum elongation in the planc of the shcct was obtained from cross- rolled hot-forged powder. Coldbend tents were able to distinguish between unidirectionally rolled and cross-rolled sheet. The degree of bend proved to be sensitive to strip width and, irrespective of tensile ductility, became negligible above a width of 0.2 ins. for all types of sheet of thickness 0.030 ins. bent around a 3/32 in. radius. Wide strips of certain types of fabricated sheet were bent at 650-C using a mild-steel supporting plate or at 300 d C unsupported. (auth)
