Sigma Phase Formation

Sigma Phase Formation is a metallurgical phenomenon classified as an intermetallic phase precipitation process, distinguished by the nucleation and growth of a brittle, chromium-rich σ-phase at grain boundaries in stainless steels and nickel-based alloys under specific temperature exposures, thereby predisposing the material to intergranular corrosion.
