Rolling Texture Formation in Super-Duplex Stainless Steel
The present research is a part of project which concerns a deformation behavior of duplex type ferritic-austenitic stainless steels. This paper focuses on the examination of ferrite and austenite textures formed upon thermo-mechanical treatment and deformation textures developed during cold-rolling of super-duplex stainless steel sheet. The character and stability of the textures observed in both phases over a wide deformation range are the result of two-phase morphology formed upon hot- and subsequent cold-rolling. The specific band-like morphology of the ferrite-austenite structure creates different conditions for plastic deformation due to the interaction of both phases and considerably constrained lattice rotations. That is why the processes governing the texture formation in duplex steels are supposed to change in comparison to single phase steels affecting final rolling textures of ferrite and austenite.
