Degradation of nanostructured bainitic steel under rolling contact fatigue [PDF]
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2014 Abstract The consequences of rolling contact fatigue on a carbide-free nanostructured bainitic steel intended for bearing applications are presented for the first time. Tests performed at various intervals followed by mechanical, microscopical, and crystallographic characterization lead to the conclusion that the degradation mechanism is ductile void

Effect of tempering upon the tensile properties of a nanostructured bainitic steel [PDF]
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2014 Abstract The tensile properties of a nanostructured carbide-free bainitic steel formed at 200–250 °C are compared against those after tempering sufficiently to remove the retained austenite. Although significant ductility is observed following tempering, a comparison of tempered and untempered samples shows that it is in fact reduced when a ...

Infusion of hydrogen into nanostructured bainitic steel [PDF]
Materials Characterization, 2017 The trapping of hydrogen in nanostructured bainitic steel has been investigated using thermal desorption analysis, in order to determine the potency of the ferrite-retained austenite (α/γ) interfaces and retained austenite as trapping sites. Thermal desorption data showed that the volume of retained austenite is more effective in trapping hydrogen than

Electrochemical corrosion behaviour of nanostructured bainitic steel [PDF]
, 2014 Nanostructured bainitic steels are gaining high interest due to their excellent mechanical properties. However, high carbon content in nanostructured bainitic steels can influence their general and localized corrosion susceptibility. In this study, the corrosion behaviour of nanostructured bainitic steel was compared with the well-known martensitic ...
