Structure and Mechanical Properties of Fine-Grain Formed Beryllium,

Abstract

The method of programmed different-direction deformation of 99.9 percent pure cast beryllium was used to obtain metal with a grain size of 13 mu m. Its mechanical properties under tension were determined in the 20-1000 degrees centigrade region. At room temperature the tensile strength equalled 56.5 kgf/sq. mm and the relative elongation was 7.5 percent. At the moment of compression testing strength reached 150 kgf/sq. mm; there was no destruction at a deformation of approximately 50 percent. (Author)
