Beryllium Research and Development Program

Abstract

The strength and ductility above room temperature of the hot-presses Brush and Pechiney powders being studied at Lockheed show the usual behavior for beryllium. This material exhibits little response to aging heat treatments. Extruded Brush and Pechiney beryllium possess greater strength and ductility in the transverse direction than in the longitudinal direction at temperatures below about 20 C. This appears to be due to twinning in the longitudinal specimens. Tensile specimens are being prepared at Nuclear Metals from single crystals of SR Pechiney and of single distilled beryllium. These crystals were obtained from metal melted and slowly cooled in BeO crucibles.
