Effect of interlayer temperature on microstructural evolution and deformation mechanisms of high-manganese steel fabricated by wire arc additive manufacturing: An in-situ neutron diffraction study

Key Points

• Microstructural evolution is significantly influenced by interlayer temperature during additive manufacturing.
• Increased interlayer temperature leads to enhanced ductility in high-manganese steel, improving its performance.
• In-situ neutron diffraction analysis sheds light on the deformation mechanisms at varying temperatures.
• Understanding these mechanisms is crucial for optimizing additive manufacturing processes in steel fabrication.
