| Abstract Scope |
This work investigates texture evolution in austenitic steels exhibiting TRIP/TWIP effects using a combined experimental–simulation approach. In-situ synchrotron X-ray diffraction (SXRD) and neutron diffraction (ND) are used to track phase fractions and orientation changes during deformation in high-manganese, 304, and 316 steels. The focus is on the interplay between FCC γ-austenite, HCP ε-martensite, and BCC α′-martensite. The experimental results are compared with MTEX-based simulations that incorporate deformation twinning and transformation-induced texture components. The study highlights the strengths of combining SXRD and ND for capturing microstructural changes and demonstrates the potential of MTEX simulations to support a deeper understanding of complex texture evolution in multi-phase steels under mechanical loading. |
