A novel quenching and partitioning process (Q&P) including the hot straining process (HS) has been recently introduced as an alternative to optimize mechanical properties in TRIP-assisted steel, which is of great interest to the automotive industry. This combination of processes is here called Hot Straining and Quenching and Partitioning process (HSQ&P). In this work, two Q&P conditions and four thermomechanical treatments (HSQ&P) were studied, using two straining temperatures (750 °C – HSQ&P750, and 800 °C – HSQ&P800) and two quenching temperatures (318 °C and 328 °C). The partitioning step was performed at 400 °C for 100 s in all cycles. Microstructural features were comprehensively studied using electron backscattered diffraction and nanoindentation techniques. HSQ&P samples showed a good combi.. Read More»
