Quenching and Partitioning of Multiphase Aluminum-Added Steels [PDF]
Metals, 2019 The quenching and partitioning response following intercritical annealing was investigated for three lean TRIP-type high-Al steel compositions. Depending on the intercritical austenite fraction following annealing, the steels assumed either a ferrite ...

Influence of carbon partitioning kinetics on final austenite fraction during quenching and partitioning [PDF]
Scripta Materialia, 2009 The quenching and partitioning (QP extension of this methodology to include carbon partitioning kinetics is developed here. The final austenite fraction is less sensitive to quench temperature than previously predicted, in agreement with experimental results.

The "quenching and partitioning" process: background and recent progress [PDF]
Materials Research, 2005 A new process concept, "quenching and partitioning" (Q&P) has been proposed recently for creating steel microstructures with retained austenite. The process involves quenching austenite below the martensite-start temperature, followed by a partitioning ...

Materialia, 2019 Abstract Medium-Mn Quenching & Partitioning (Q&P) steels have been recently considered as potential candidates for the 3rd generation advanced high-strength steels. The processing of these steels aims to induce the partitioning of substitutional alloying elements from martensite to austenite during an isothermal treatment at high temperature, where ...

Characterization of a Medium Mn-Ni Steel Q&P Treated by a High Partitioning Temperature Cycle
Metals, 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.
