Nature of the effect of isomorphicβ-stabilizing elements on the susceptibility of titaniumα-alloys to corrosion cracking in aqueous solutions of chlorides

  • 19 Accesses

Conclusions

  1. 1.

    The reduced susceptibility of titanium alloys to corrosion cracking in solutions of chlorides upon introduction of β-stabilizers is connected with the suppression of segregation of α2-phase, and it depends on the supersaturation of α-solid solution with β-stabilizers.

  2. 2.

    The concentration of α-phase, and correspondingly the sensitivity to CC are determined by the conditions of hot forming and heat treatment of the semiproducts. The effectiveness of alloying is ensured by limiting the heating time in the high-temperature part of the (α+β)-region. Annealing or plastic deformation in the β-region are decisive for the greatest effectiveness of alloying.
