Intercrystalline corrosion

Client: rupertharris

Location: Glossary

Corrosion which occurs preferentially along dendrite boundaries. This type of attack is caused by chemical differences between the dendrites and the material which surrounds them. In cast tin bronzes, the dendrites are alpha copper-tin, higher in copper, and the interdendritic material is usually mixed alpha-delta eutectoid, higher in tin. Interdentritic corrosion is caused by the chemical difference between these two materials.
