The conventional production of high-manganese steels is very demanding regarding the process technology. Twin-roll strip casting, however, represents a promising alternative for the energy-efficient production of such high-alloyed steels. This work deals with challenges of strip casting of aluminum-alloyed high manganese steels and the further processing to recrystallized cold strip. A thermomechanical treatment consisting of up to 70% cold rolling and subsequent annealing has been developed, which results in a recrystallized cold strip with a fine grained microstructure (mean grain size ~3 Ám). The annealed cold strip shows remarkable mechanical properties with a yield strength of 485 MPa and an ultimate tensile strength of 980 MPa at 57 % engineering strain. Forming limit curves were determined by Nakajima tests to further evaluate the formability in case of multi-axial loading.
