Microstructural Evolution and Dynamic Partitioning Behavior in Quenched and Partitioned Steels

steel research international, 2017
Direct quenching and dynamic partitioning (DQ&P) process is a promising approach and there continues to be lack of understanding concerning cooling condition in the hot strip rolling line. Here, the authors have simulated DQ&P process in low carbon Si–Mn steel using a thermal simulator.

Quenching and partitioning steel produced through hot rolling, direct quenching and annealing

Materials Science and Technology, 2016
A novel type of quenching and partitioning steel was developed using direct quenching after hot finishing rolling, followed by intercritical annealing, quenching and partitioning (DQ–Q&P) process. The desirable combination of strength and ductility was obtained.

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 ...

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.

Microstructure Characterization of Quenching and Partitioning Steels

Materials Science Forum, 2018
A steel containing Fe-0.2C-2Mn-Si-Al was annealed using intercritical Q&P cycles. Quenching temperature and partitioning time at 440°C was varied. Analysis of microstructure evolution during such Q&P treatments was performed using different characterization tools: FEG-SEM, EBSD, dilatometer and saturation magnetization measurements. Especially,

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.

Effect of Interfacial Mn Partitioning on Carbon Partitioning and Interface Migration During the Quenching and Partitioning Process

Metallurgical and Materials Transactions A, 2017
A so-called QP-LE model, in which interface condition is assumed to be Local Equilibrium (LE), has been proposed to evaluate the effect of interfacial Mn partitioning on interface migration and carbon partitioning during the Quenching and partitioning process (Q&P) of an Fe-0.3C-3.0Mn-1.5Si (wt pct) alloy.

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 the partitioning of interstitials C and N to the austenite at or above the quenching temperature ...
