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

open access: yesMetals, 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]

open access: yesScripta Materialia, 2009
The quenching and partitioning (QP extension of this methodology to include carbon partitioning kinetics is developed here. The final austenite fraction is less sensitive to quench temperature than previously predicted, in agreement with experimental results.

Austenite decomposition and carbon partitioning during quenching and partitioning heat treatments studied via in-situ X-ray diffraction [PDF]

open access: yesMaterials & Design, 2019
High strength combined with excellent ductility can be achieved by quenching and partitioning (Q&P) microstructures containing martensite and a considerable amount of retained austenite.

The "quenching and partitioning" process: background and recent progress [PDF]

open access: yesMaterials 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 ...

Characterization of a Medium Mn-Ni Steel Q&P Treated by a High Partitioning Temperature Cycle

open access: yesMetals, 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.

Effects of Si addition on microstructure and properties of martensitic stainless steel treated by quenching and partitioning process

open access: yesCailiao gongcheng, 2021
In order to improve the strength-plasticity and corrosion resistance, two nitrogen-alloyed martensitic stainless steels 10Cr13N and 10Cr13Si2N with different Si contents were designed and fabricated.
