Effect of recrystallization temperature on the mechanical properties of beryllium
The grain size of beryllium is not a single-valued characteristic of the structure; the mechanical properties also depend on the substructure.
The reduction of the yield strength with increasing recrystallization temperatures is due to a reduction of the dislocation density.
The increase of the activation volume with increasing annealing temperatures is due to the lower concentration of impurities in the matrix.
