Influence of Parameters of Quenching and Partitioning Process on Microstructure and Fraction of Retained Austenite

Journal of Advanced Materials in Engineering, 2015
Certain amount of retained austenite can increase ductility of steels because of the TRIP phenomenon during plastic deformation. One method for achieving this is partitioning of carbon into austenite to stabilize it at room temperature. The quenching and

Advantages of intercritically annealed quenching and partitioning (IQ&P) process in 4Mn steel

Journal of Materials Research and Technology
For 4Mn steel, the deterioration of austenite stability caused by insufficient Mn content and the neglect of strength in intercritical annealing (IA) process are the main reasons limiting its application.

Partitioning-related microstructure evolution and mechanical behavior in a δ-quenching and partitioning steel

Journal of Materials Research and Technology, 2022
The splitting of the quenching and partitioning of quenching - tempering & partitioning (Q-T&P) process permits us to investigate the as-quenched and partitioned states of the novel δ-quenching & partitioning (δ-QP) steel, separately.

Effect of partitioning time on one-step quenching and partitioning steel

Journal of Physics: Conference Series, 2022
The microstructure and mechanical properties of one-step quenching and partitioning (Q&P) steel with different partitioning time were analyzed. The results shows that the elongation rate rises, tensile strength decreases, the yield strength first declines and then increases with the increasing partitioning time (PT).
