BAINITE : OVERALL TRANSFORMATION KINETICS

open access: yesLe Journal de Physique Colloques, 1982
New experimental results on the overall transformation kinetics of the bainite reaction (in three different steels) are interpreted in terms of recent work on the transformation mechanism of bainite. The analysis is shown to be consistent with (a) a linear dependence of the activation energy for isothermal nucleation, on the transformation free energy ...

Metastable Austenite Transformation Kinetics of Medium-Carbon Silicon-Rich Steel during Partitioning in a Q & P Process

open access: yesMetals, 2020
In the present study, quenching and partitioning (Q & P) treatment of a medium-carbon silicon-rich steel was processed by a dilatometer. The volume fraction of the retained austenite at different partitioning times was determined by X-ray diffraction ...

The Effect of Direct Strip Casting on the Kinetics of Phase Transformation of a Dual Phase Steel

open access: yesMetals, 2022
A dual phase steel has been produced directly from the liquid under conditions that simulate direct strip casting and thin slab casting. The kinetics of polygonal ferrite formation during the inter-critical anneal were quantified using the JMAK approach,

Crystallization kinetics of poly(lactic acid)-talc composites [PDF]

open access: yes, 2011
The crystallization kinetics of Poly(lactic acid) / talc composites were determined over a range of 0 wt.% to 15 wt.% of talc. Talc was found to change the crystallization kinetics.

Study on Non-Isothermal Transformation of Ti-6Al-4V in Solution Heating Stage

open access: yesMetals, 2019
In order to understand the non-isothermal transformation behavior of Ti-6Al-4V titanium alloy in the continuous heating stage of solution treatment, thermal dilatometry tests with heating rates of 0.1~0.8 °C/s were designed.

Tensorial stress-plastic strain fields in α-ω Zr mixture, transformation kinetics, and friction in diamond anvil cell [PDF]

open access: yes, 2022
Various phenomena (phase transformations, chemical reactions, and friction) under high pressures in diamond anvil cell are strongly affected by fields of all components of stress and plastic strain tensors. However, they could not be measured.
