Conclusions

  1. 1.

    A phase diagram was plotted for the Mg−Tb system with up to ∼45% Tb. The phase diagram is characterized by substantial solubility of terbium in solid magnesium (up to 24%), which decreases with temperature.

  2. 2.

    Mg−Tb alloys are hardened considerably during aging. High strength characteristics are obtained in the aged condition with a terbium concentration close to its maximum solubility in solid magnesium: σb > 40 kgf/mm2
