Into the quenching & partitioning of a 0.2C steel: An in-situ synchrotron study [PDF]

Materials Science and Engineering: A, 2019
Abstract Quenching and partitioning (Q&P) is an effective way for retaining austenite at room temperature. The actual mechanisms responsible for austenite stabilization are still under debate, since it is impossible to track carbon diffusion with the conventional metallographic tools.

Interaction of martensite and bainite transformations and its dependence on quenching temperature in intercritical quenching and partitioning steels

Materials & Design, 2019
A series of quenching temperatures (QT) were applied to investigate the interaction of bainite and martensite transformations in intercritical quenching and partitioning steels with multiple-stage martensite transformation.

Development of a new generation of quench and partitioning steels: Influence of processing parameters on texture, nanoindentation, and mechanical properties

Materials & Design, 2020
A novel quenching and partitioning process (Q&P) including the hot stamping (HS) process was studied, using two stamping temperatures (750 °C and 800 °C) and two quenching temperatures (318 °C and 328 °C). This combination is here called Hot Stamping and

Non Photochemical Quenching mechanism in higher plants and in the unicellular alga Chlamydomonas reinhardtii [PDF]

, 2010
Light is a necessary ecological factor for oxygenic photoautotrophic organisms. Plants and algae require light for life but it can sometimes become a limiting factor or even cause stress events.

Processing Variants in Medium-Mn Steels

Metals, 2019
This paper highlights some recent efforts to extend the use of medium-Mn steels for applications other than intercritically batch-annealed steels with exceptional ductility (and strengths in the range of about 1000 MPa).

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

Inhibition of cyclin‐dependent kinases 12/13 using CT7439 as a treatment for colorectal cancer with CDK12 upregulation

Molecular Oncology, EarlyView.
The proposed mechanism of action for the CDK12/13 inhibitor and cyclin K degrader, CT7439. CDK12/13 inhibition interrupts transcription elongation, leading to increased DNA damage that results in cell death. This agent is a potentially novel treatment option for patients with colorectal cancer. Created in BioRender. Cyclin‐dependent kinase (CDK) 12 and

Microstructure Evolution and Competitive Reactions during Quenching and Partitioning of a Model Fe–C–Mn–Si Alloy

Metals, 2020
The mechanisms behind the carbon enrichment of austenite during quenching and partitioning are still a matter of debate. This work investigates the microstructural evolution during the quenching and partitioning of a model Fe−C−Mn−Si ...
