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

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.

The Thermal Stability of Quenched and Partitioned Steel Microstructures [PDF]

open access: yessteel research international, 2021
The quenching and partitioning (Q&P) process is a heat treatment process, aiming at the creation of steel microstructures composed of martensite and retained austenite. Herein, the thermal stability of the microstructure is investigated upon reheating steel microstructures, created with different Q&P settings, in different thermal routes, using

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 ...

Heat Treatment Design for a QP Steel: Effect of Partitioning Temperature

open access: yesMetals, 2021
Designing a new family of advanced high-strength steels (AHSSs) to develop automotive parts that cover early industry needs is the aim of many investigations. One of the candidates in the 3rd family of AHSS are the quenching and partitioning (QP) steels.

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 ...

Microstructure and mechanical property relationship in a high strength high-Al low-Si hot-dip galvanized steel under quenching and partitioning process

open access: yesJournal of Materials Research and Technology, 2020
We elucidate here profound effects of quenching and partitioning process on the microstructure and mechanical properties of high strength hot-dip galvanized steel with high Al and low Si content. The results indicated that partitioning time significantly
