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 ...

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, 2019Quenching 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 ...

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 ...

Microstructural Evolution and Dynamic Partitioning Behavior in Quenched and Partitioned Steels
steel research international, 2017Direct 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.
