Austenite Reverse Transformation in a Q&P Route of Mn and Ni Added Steels

Metals, 2020
In this work, four low carbon steels with different contents of Mn and Ni were heat treated by quenching and partitioning (Q&P) cycles where high partitioning temperatures, in the range of 550 °C–650 °C, were applied.

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

, 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.

Overview of mechanisms involved during the quenching and partitioning process in steels

, 2011
The application of the quenching and partitioning (Q&P) process in steels involves a microstructural evolution that is more complex than just the formation of martensite followed by carbon partitioning from martensite to austenite.

Effect of Quenching and Partitioning Heat Treatment on Ductile Cast Irons

MATEC Web of Conferences, 2016
In this study, the ductile cast irons were prepared by the melting process and then carried out the quenching and partitioning heat treatment. The microstructures were observed by both an optical microscopy and a field emission scanning electron ...

Observation of an Isothermal Transformation during Quenching and Partitioning Processing

, 2018
The kinetics of the isothermal transformation, which occurs during a single-step quenching and partitioning (Q and P) process, was analyzed by means of dilatometry. Experiments revealed that an isothermal transformation with very specific characteristics
