Conclusions

  1. 1.

    In Be-Cr alloys in equilibrium with phase based on beryllium there is a phase based on CrBe12, which is formed by the peritectic reaction: L+CrBe2⇌CrBe12. The composition of the compound is evidently close to the composition at the peritectic point on the phase diagram.

     
  2. 2.

    The position of the eutectic point on the phase diagram was determined more precisely from the beryllium side. Eutectic solidification occurs at 1240+10° in the alloy containing 13.8% Cr.

     
  3. 3.

    Binary beryllium alloys containing up to 13% Cr have relatively low strength, not exceeding 10–11.6 kgf/mm2. When nickel or vanadium is added to the alloy of beryllium with chromium the strength rises to 14–17 kgf/mm2. The ductility of these alloys is low.
