Conclusions

  1. 1.

    The susceptibility of aluminum alloys to delayed fracture is connected with the nonuniform decomposition of the solid solution and its low stability. The service life of a part is the shorter the higher the anisotropy of grain boundary fracture, the higher the level of residual stresses, and the lower the threshold stress in the tests for corrosion cracking.

  2. 2.

    The susceptibility of aluminum alloys to corrosion cracking can be eliminated or considerably reduced by using controlled cooling in quenching in combination with artificial aging.
