PREPARATION AND EVALUATION OF HIGH PURITY BERYLLIUM

Abstract

The purpose of this investigation is to produce high purity beryllium and to study its deformation and fracture characteristics. The zone melting of one inch diameter bar was completed. A single crystal specimen of a copper beryllium alloy containing 5 weight per cent copper was tested in tension with the crystal oriented for basal glide. This specimen exhibited a CRSS on the basal plane of 7800 PSI and underwent a 19% reduction in area, equivalent to 23% elongation, over about one half the gage length of the specimen prior to fracture.
