Quenching and Partitioning of Multiphase Aluminum-Added Steels [PDF]

Metals, 2019
The quenching and partitioning response following intercritical annealing was investigated for three lean TRIP-type high-Al steel compositions. Depending on the intercritical austenite fraction following annealing, the steels assumed either a ferrite ...

Influence of carbon partitioning kinetics on final austenite fraction during quenching and partitioning [PDF]

Scripta Materialia, 2009
The quenching and partitioning (Q&P) process is a two-stage heat-treatment procedure proposed for producing steel microstructures that contain carbon-enriched retained austenite.

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

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.
