“…It Earlier, the precipitation of various phases in beryllium of technical purity during heat treatment was observed [1,3,[11][12][13][14][15]. In the usual working state, after preparatory technological annealing, technical beryllium usually has a Mössbauer spectrum consisting of doublet lines of solid solution and one or two secondary phases.…”

The example of beryllium of technical purity shows the possibility of introducing changes in the distribution of impurities between different phases during the operational period. The feeding and prolongation of the active action of one of the secondary phases, which favorably affects the properties of the material, is carried out. The data on the redistribution of iron and aluminum impurities were obtained by Mössbauer spectroscopy. Spectra were received after homogenization, at the intermediate stages and after completion of isothermal annealing at 600 ∘ C with the total endurance of more than 1100 h. The intermediate secondary phase AlFeBe 4 prevails during more long-lived time term than with the ordinary content of aluminum.Methods for correcting the distribution of impurities are discussed.
