Twin-roll strip casting represents a promising alternative for the production of high manganese steels. The present work demonstrates the opportunities for the production and further processing of a Fe-17Mn-0.6C-1.5Al TWIP steel. The mechanical properties are increased along the process chain and the cold strip exhibits a true stress of σ = 1500 MPa at a logarithmic strain of ɛ = 0.5. Combined EPMA and EBSD measurements allow for analyzing the influence of the inhomogeneous as-cast structure with pronounced microsegregations on twinning behavior. It was shown that twinning starts in the areas with a lower element concentration and thus with a lower local stacking fault energy. In addition, the fine as-cast structure with segregations only on the micron-scale has no negative influence on the resulting mechanical properties in the recrystallized cold strip.
