Characteristics of bainitic transformation and its effects on the mechanical properties in quenching and partitioning steels

Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2021
Steel treated by quenching and partitioning exhibits an excellent combination of strength and ductility by taking advantage of the transformation-induced plasticity effect of retained austenite.

Effect of boron on bainitic transformation kinetics after ausforming in low carbon steels

Journal of Materials Science and Technology, 2017
The addition of boron (B) is frequently adopted to increase the hardenability of bainitic steels. Although it is well known that B can retard the bainitic transformation kinetics, it is still not clear how the B affects the bainitic transformation ...

Critical ausforming temperature to promote isothermal bainitic transformation in prior-deformed austenite

Materials Science and Technology, 2019
The effects of deformation temperature on phase transformation and microstructure in nanostructured bainite steel were studied. The results indicate that the deformed austenite with a strain of 0.3 at 300°C presents accelerated kinetics of bainitic ...

Effect of ausforming on the anisotropy of low temperature bainitic transformation

Materials Characterization, 2018
Ausforming is the process by which austenite is plastically deformed prior to bainitic or martensitic transformation. The advantages of such a process on the kinetics of the bainitic transformations have already been reported, but little is found about ...

The mechanism of bainite transformation

Journal de Physique IV (Proceedings), 2003
Ultra-fine structures of bainite and its surface relief, and carbide nucleation inside austenite at the interface of ferrite/austenite are studied in this paper. The sympathetic nucleation and ledgewise growth theory is applied to explain the experimental results.

Modeling retained austenite in Q&P steels accounting for the bainitic transformation and correction of its mismatch on optimal conditions

Acta Materialia, 2020
Modeling retained austenite in quenching and partitioning (Q&P) steels remains a challenge, and the conventional ‘constrained carbon equilibrium’ (CCE) model fails to predict the optimal condition for achieving the maximal amount of retained austenite in

Kinetics of the bainite transformation

Proceedings of the Royal Society of London. Series A: Mathematical, Physical and Engineering Sciences, 2004
Summary: A theory is developed for the evolution of bainite as a function of time, temperature, chemical composition and austenite grain size. The model takes into account the details of the mechanism of transformation, including the fact that nucleation begins at the austenite grain surfaces, and that the growth of a sheaf occurs by the repeated ...
