Understanding Intercrystalline Corrosion by lu190765 is a document available to read on EtoBox.
Intercrystalline corrosion occurs along grain boundaries in metals where the boundaries are depleted of corrosion-resistant elements. In stainless steels and nickel alloys, chromium carbide precipitation at grain boundaries during high-temperature processes causes chromium depletion zones that are susceptible to corrosion. The corrosion propagates along the depleted grain boundaries. Stabilization with elements like titanium and niobium that form preferential carbides can prevent intercrystalline corrosion,
