Carbon Partitioning During Quenching and Partitioning Heat Treatment Accompanied by Carbide Precipitation

Acta Materialia, 2015
Abstract Carbon partitioning from martensite into austenite in the quenching and partitioning (Q&P) process has been suggested to be controlled by the constrained carbon equilibrium (CCE) criterion. It defines an approach for predicting the carbon concentration in austenite under the condition that competing reactions such as carbide formation and ...

Quenching and Partitioning Processing of Transformable Ferritic Stainless Steels

Scripta Materialia, 2011
Austenite was stabilized at room temperature in a low-interstitial 16%Cr transformable ferritic stainless steel by quenching from the intercritical annealing temperature to below the martensite start temperature of the intercritical austenite prior to ...

Unambiguous Carbon Partitioning From Martensite to Austenite in Fe–C–Ni Alloys During Quenching and Partitioning

Scripta Materialia, 2013
International audienceThe mechanism of carbon enrichment in retained austenite during the quenching and partitioning (Q&P) process is still controversial.

On the role of Manganese Partitioning in Metastable Austenite by Quenching and Partitioning Treatment

steel research international, 2023
With the aim to study the role of “frozen” concentration gradient of manganese (Mn) element in stability of retained austenite (RA) with multiple‐stage martensite transformation, a series of intercritical annealing (IA) temperatures is conducted before quenching and partitioning (Q&P) treatment.

Quenching and Partitioning of Plate Steels: Partitioning Design Methodology

Metallurgical and Materials Transactions A, 2019
Quenching and partitioning (Q&P), a new heat treatment concept to develop high-strength martensitic microstructures with retained austenite (RA), has been implemented industrially to make sheet products. This process is also of interest for thicker plate products, to employ transformation-induced plasticity to enhance toughness and/or wear resistance ...

Comparison of the Impact Wear Performances of Quenching and Partitioning and Quenching and Tempering Steels

steel research international, 2021
A low‐carbon, high‐strength steel is treated by different quenching and partitioning (QP) and quenching and tempering (QT) routes in a salt bath furnace, and its wear performance is evaluated by impact abrasive wear tests. It is observed as compared with the traditional QT steel; the QP steel manifests better wear performance at the quenching ...

Carbon and strain partitioning in a quenched and partitioned steel containing ferrite

Acta Materialia, 2019
Abstract We applied a hot rolling direct quenching and partitioning (HDQ&P) process to a low-C low-Si Al-added steel and obtained a Q&P steel containing 40 vol % of ferrite. Microstructure characterization was performed by means of SEM, EBSD, TEM and XRD.

Quenching and Partitioning: Science and Technology

2013
A lecture given by John Speer, at the Adventures in the Physical Metallurgy of Steels (APMS) conference held in Cambridge University. The quench and partitioning process involves partial transformation to martensite, followed by an increase in temperature to permit the excess carbon to partition into the residual austenite.
