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.

Effects of Compositional Inhomogeneity on the Microstructures and Mechanical Properties of a Low Carbon Steel Processed by Quenching-Partitioning-Tempering Treatment

open access: yesCrystals, 2022
Quenching-partitioning-tempering (Q-P-T) heat treatment is a relatively novel approach to attain excellent ductility in high-strength steels. In the present work, the microstructural evolution and the mechanical properties of a low carbon microalloyed ...

Formal Equivalence Between Partitioned and Partition-Free Quenches in Quantum Transport [PDF]

open access: yesJournal of Low Temperature Physics, 2018
In this paper we review the partitioned and partition-free approaches to the calculation of the time-dependent response of a molecular junction to the switch-on of an arbitrary time-dependent bias. Using the non equilibrium Green's function formalism on different time contours, we derive a formal equivalence between these two approaches. This clarifies

Quenching and Partitioning Steel Heat Treatment [PDF]

open access: yesMetallography, Microstructure, and Analysis, 2013
Abstract Quenching and partitioning (Q&P) steel is a term used to describe a series of C-Si-Mn, C-Si-Mn-Al, or other steels subjected to the quenching and partitioning heat treatment process. This article discusses the Q&P steel's chemical compositions and mechanical properties, and provides an overview of the important ...

Critical Assessment 7: Quenching and partitioning [PDF]

open access: yesMaterials Science and Technology, 2015
Quenching and partitioning is a relatively new heat treatment concept to generate microstructures containing retained austenite stabilised by carbon partitioning from martensite. Research on quench and partitioning has been conducted by numerous groups, and this critical assessment provides some of the authors’ perspectives on progress and ...

Effect of Innovative Quenching-Partitioning Heat Treatment on Microstructure and Hardness Properties of Medium Carbon Steel According to Traditional Quenching-Tempering Heat Treatment

open access: yesMehmet Akif Ersoy Üniversitesi Fen Bilimleri Enstitüsü, 2019
Ductility in the formability of the steels is the desired material property. It is possible to obtain the desired ductility by the traditional quenching-tempering heat treatment which is often used in industry.

Effect of partitioning time on one-step quenching and partitioning steel

open access: yesJournal of Physics: Conference Series, 2022
The microstructure and mechanical properties of one-step quenching and partitioning (Q&P) steel with different partitioning time were analyzed. The results shows that the elongation rate rises, tensile strength decreases, the yield strength first declines and then increases with the increasing partitioning time (PT).
