Journal of Nanomaterials, Volume 2023, Issue 1, 2023., 2023 The fabrication of SS (stainless steel)‐UO2 cermet‐type advanced nuclear fuel pellets suitable for use in power reactors depends on the development of metallic (SS), ceramic (UO2), and cermet (SS‐UO2) microspheres with special characteristics. In this work, a nonconventional powder metallurgy process was developed to produce porous SS microspheres ...

steel research international, Volume 92, Issue 6, June 2021., 2021 A new medium manganese steel with vanadium addition for automotive forging application is presented. The steel is alloyed with 4 wt% aluminum to assure a complete martensitic microstructure after air‐cooling. The investigated laboratory melt (80 kg), reaches a yield strength of 892 MPa and a Charpy‐V notch impact toughness of 48 J in the air‐cooled ...

Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2009 An alloy system based on iron is described in which it has been possible to create a high density of interfaces by heat treatment alone. The resulting structure consists of a mixture of slender platelets of bainitic ferrite, just 20–40 nm in thickness, embedded in a matrix of carbon-enriched austenite.

Distribution of Dislocations in Nanostructured Bainite
Solid State Phenomena, 2011 The dislocation density in ferrite and austenite of a bainitic microstructure obtained by transformation at very low temperature (300 °C) has been determined using transmission electron microscopy. Observations revealed that bainitic ferrite plates consist of two distinctive regions with different substructures. A central region in the ferrite plate is

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
