Conclusions

  1. 1.

    The grain size of beryllium is not a single-valued characteristic of the structure; the mechanical properties also depend on the substructure.

     
  2. 2.

    The reduction of the yield strength with increasing recrystallization temperatures is due to a reduction of the dislocation density.

     
  3. 3.

    The increase of the activation volume with increasing annealing temperatures is due to the lower concentration of impurities in the matrix.
