A program was initiated with the aim of producing randomly oriented beryllium sheet. Rolling experiments are being conducted with billets of hot- pressed polycrystalline material. The variables being studied include rolling and annealing temperatures, per pass and total per cent reductions, and the effect of specimen geometry on deformation. In anticipation of considerable x- ray work, the effect of specimen thickness on x-ray intensity is being studied. single crystals have been obtained by vacuum casting lump beryllium and carefully cutting the individual crystals from the parent ingot. A Unitron Vacuum Heating Stage and a Huribut Counter have been adapted for use with a Bausch and Lomb research metallograph for determination of recrystallization kinetics and study of twin absorption.
