EBSD study of a hot deformed austenitic stainless steel

► Microstructural characterization of an austenitic stainless steel by EBSD. ► The role of twins in the nucleation and growth of dynamic recrystallization. ► Grain refinement through the discontinuous dynamic recrystallization. ► Determination of recrystallized fraction using the grain average misorientation. ► Relationship between recrystallization and the frequency of high angle boundaries.
