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 kgfsq. mm and the relative elongation was 7.5 percent. At the moment of compression testing strength reached 150 kgfsq. mm there was no destruction at a deformation of approximately 50 percent. Author
