Article
Metallic materials, especially steel, underpin transportation technologies. High-manganese twinning induced plasticity (TWIP) austenitic steels exhibit exceptional strength and ductility from twins, low-energy microstructural defects that form during plastic loading. Their high-strength could help light-weighting vehicles, and hence cut carbon emis...

Article
We have performed high-resolution structural and chemical characterization of the native oxide films formed on a ferritic Fe- 13 at. % Cr alloys at different stages of growth. The steady-state protective oxide film was found to be 5-6 nm thick, epitaxially grown, with a cubic spinel-structure ((Fe, Cr)3O4) and a Baker-Nutting orientation-relationsh...
Article
The selective removal of a less noble (more chemically active) metal from a mixture of 2–3 metals can yield a bicontinuous, open-pore, 3D nanoporous metal (NPM), that is rich in the more noble metal(s) ¹ . NPMs have been successfully developed by the intelligent use of the conventionally-undesired dealloying corrosion. The excellent properties of N...
Preprint
High-manganese twinning-induced plasticity (TWIP) steels exhibit mechanical properties making them attractive for structural applications. However, they are prone to hydrogen embrittlement (HE), and may undergo a brittle, catastrophic failure upon hydrogen ingress in service conditions. We investigated the he susceptibility of a Fe28Mn0.3C (wt.%) T...

Hydrogen embrittlement can cause a dramatic deterioration of the mechanical properties of high-strength metallic materials. Despite decades of experimental and modelling studies, the exact underlying mechanisms behind hydrogen embrittlement remain elusive. To unlock understanding of the mechanism and thereby help mitigate the influence of hydrogen...

Numerous metallurgical and materials science applications depend on quantitative atomic-scale characterizations of environmentally-sensitive materials and their transient states. Studying the effect upon materials subjected to thermochemical treatments in specific gaseous atmospheres is of central importance for specifically studying a material’s r...

Quantitative characterization of environmentally-sensitive materials and their transient states after being subjected to thermal treatment in specific gaseous atmospheres at near-atomic scales is of vital importance for numerous metallurgical and materials science applications, such as corrosion, hydrogen embrittlement, catalysis, reduction and sur...

Evolution of microstructure in the patented near-eutectoid steel, forged under varying situations, is critically examined in the present investigation. Steel with 0.74 wt.% carbon is isothermally annealed at 500 °C to obtain fine pearlite microstructure. Steel samples, so patented, are subjected to mechanical deformation by forging at various tempe...
Article
Full-text available
Recently, a new metallic alloy design concept has been introduced for developing novel materials for multifunctional applications which are commonly near equiatomic multicomponent alloys having at least five principal elements. These materials have been popularly known as high-entropy alloys (HEAs) due to their innate high configurational entropies...
