Characterization of the anisotropic necking in duplex stainless steels with lamellar microstructures

Duplex stainless steels are characterized by oriented microstructures, in which its constituent phases, ferrite (α) and austenite (γ) form layered or fibrous phase arrangements depending on forming operations (e.g. rolling). These microstructures have the potential to induce anisotropy in the macroscopic mechanical properties of the material. A very interesting phenomenon related to this microstructurally-induced anisotropy is the subject of...
