Induced martensitic transformation during tensile test in nanostructured bainitic steels [PDF]

Materials Science and Engineering: A, 2016
Retained austenite in nanostructured bainite is able to undergo mechanically induced martensitic transformation. However, the link between transformation and deformation mechanisms involved makes difficult the understanding of the process. In this work, a model has been developed to assess the effect of the external stress itself on the martensite ...

Estimation of the Volume Percent of Normal and Nanostructured Bainite in Bainitic Steels

Materials Today: Proceedings, 2015
Abstract Estimation of the volume percent of bainite has been conducted using a powerful computational technique known as neural network. The model is proposed for ordinary bainitic steel in addition to the more recent class of super bainite steel which are attractive for many applications.

The substitution of aluminum for cobalt in nanostructured bainitic steels [PDF]

AIP Conference Proceedings, 2018
Two kinds of new steels are designed, in which the only difference is the use of the alloy element aluminum instead of cobalt. The effect of cobalt and aluminum addition on the microstructure and mechanical properties of high-carbon nanostructured bainitic steels was studied. The microstructure and mechanical properties achieved by a low temperature au

Microstructure evolution during tensile deformation of a nanostructured bainitic steel [PDF]

Scripta Materialia, 2013
In situ neutron diffraction was used during tensile testing at room temperature to examine the changes in the proportion and texture of both ferrite and austenite in a nanocrystalline bainitic steel transformed at two different temperatures, 200 and 300 C, for different times to achieve the same phase percentages.
