Abstract

The basic laws of the development of intergranular corrosion of aluminum alloys after full-scale and full-scale accelerated tests in a moderately warm climate of the coastal zone depending on the alloying system are considered. The effect of the geometric grain sizes of alloys of various systems on the depth of the MCC is shown. The dependences of the loss of mechanical properties under tension on the depth of the MCC for sheets of aluminum alloys with a thickness of 2 mm are established. The data obtained can be used to predict changes in mechanical properties under tension, depending on the degree of development of intergranular corrosion.
