Effect of Intercritical Annealing Temperature on the Final Microstructure and Mechanical Properties in a Hot-Rolled TRIP-Aided Multiphase Steel

Key Points

• Mechanical properties improve with specific intercritical annealing temperatures, enhancing steel performance.
• At 780°C, TRIP-aided steel shows superior ductility compared to lower temperatures, supporting optimal processing.
• Analysis of thermal cycles reveals significant changes in microstructure, impacting the final material properties.
• Understanding the relationship between annealing temperature and microstructure can lead to better steel design.
