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. Both quenched and partitioned steels consisted of ferrite and martensite/austenite islands.

Texture and mechanical properties of quenching and partitioning steel
Materials Research Express, 2023 Abstract Advanced high-strength steels, such as quenching and partitioning (Q&P) steels, are of considerable interest in the automotive industry owing to their desirable mechanical properties. However, further research is required to elucidate the relationship between the microstructure and mechanical properties of Q&P steels ...

Quenching and partitioning in Si/Al-free steels: effect of quenching temperature
Journal of Materials Research and TechnologyCarbon partitioning is a feasible way to stabilize austenite against martensite transformation at room temperature in quenching and partitioning (Q&P) steels. It is necessary to add Si/Al in order to inhibit competitive reactions like carbide precipitation. However, Si is harmful to Zn coating while Al is related to nozzle clogging.

The "quenching and partitioning" process: background and recent progress [PDF]
Materials Research, 2005 A new process concept, "quenching and partitioning" (Q&P) has been proposed recently for creating steel microstructures with retained austenite. The process involves quenching austenite below the martensite-start temperature, followed by a partitioning treatment to enrich the remaining austenite with carbon, thereby stabilizing it to room temperature ...

Quenching and partitioning heat treatment in ductile cast irons [PDF]
Materials Research, 2014 A commercial ductile iron alloy was submitted to a quenching and partitioning heat treatment. Samples were austenitized at 900 ºC for two hours, quenched at 160 ºC and kept at this temperature for 2 minutes and finally were re-heated at temperatures between 300 and 450 ºC during time intervals between 2 and 180 minutes.

Characterization of a Medium Mn-Ni Steel Q&P Treated by a High Partitioning Temperature Cycle
Metals, 2022 In this work, a medium Mn-Ni steel was treated through Quenching and Partitioning (Q&P) with a partitioning temperature (PT) of 650 °C, which corresponded to the start of the austenite reverse transformation (ART) phenomenon.
