Increasing the corrosion resistance of alloy AK8

Conclusions

  1. 1.

    Aging of alloy AK8 at temperatures of 170° and higher for 10–12 h improves its resistance to corrosion cracking.

  2. 2.

    To obtain high resistance to corrosion cracking (threshold stress ∼200 MPa) we recommend that alloy AK8 be aged at 175° for 24 h, which does not impair the mechanical properties or fatigue strength.

  3. 3.

    The corrosion cracking resistance of alloy AK8 is higher in a tropical marine atmosphere than in laboratory tests in 3% NaCl.
