Mechanical properties of nanostructured bainitic steels
Materialia, 2021Abstract Nanostructured bainitic steels possess ultra-high strength and have been the focus of extensive research due to their suitability in many demanding engineering applications, especially in rail-wheel system, gears, bearings and automobile industry.

Hydrogen Permeation in Nanostructured Bainitic Steel
Metallurgical and Materials Transactions A, 2016Hydrogen permeation of nanostructured bainitic steel, produced at two different transformation temperatures, i.e., 473.15 K (200 °C) BS-200 and 623.15 K (350 °C) BS-350, was determined using Devanathan–Stachurski hydrogen permeation cell and compared with that of mild steel.

Development of nanostructured steel for engineering application
International Journal of Nano and Biomaterials, 2014The increasing need for materials and steel in particular for specific applications has led to development of theories, models, software, and practices which are now of immense value in the design of steel. The world stood still recently as the first bulk nanostructured metal was produced by Tata Steel and Rolls Royce Plc.

Hydrogen-Trapping Mechanisms in Nanostructured Steels
Metallurgical and Materials Transactions A, 2013Nanoprecipitation-hardened martensitic bearing steels (100Cr6) and carbide-free nanobainitic steels (superbainite) are examined. The nature of the hydrogen traps present in both is determined via the melt extraction and thermal desorption analysis techniques.

Annealing texture of nanostructured IF steel
Materials Characterization, 2015Abstract In the present work, the evolution of annealing texture in nanostructured interstitial free steel fabricated via accumulative roll bonding (ARB) process was investigated. Textural evolution after post-annealing of ARB-processed samples was evaluated using X-ray diffraction.

Characterization of Irradiated Nanostructured Ferritic Steels
Microscopy and Microanalysis, 2007The past decade has seen the development of a new class of mechanically alloyed (MA) ferritic steels with outstanding mechanical properties that come, at least in part, from the presence of high concentrations (>10{sup 23} m{sup -3}) of Ti-, Y-, and O-enriched nanoclusters (NC).

Nanostructural Engineering of TMCP Steels
2011This paper reviews current research that aims to understand and manipulate the properties of advanced steels through control of the nanostructure, with an emphasis on thermomechanically produced steels. While the concepts of such strengthening mechanisms have been understood and used for many years, it is now possible through advanced characterisation ...

Nanostructured Strengthening of Springs and Spring Steels
Materials Science Forum, 2016The paper considers the problem of nanostructured strengthening of spring steels and springs, the idea of steel nanostructured strengthening determined not only by grain sizes but also by subgrain sizes is justified. Design schemes of thermal strain nanoscale substructure patterning in spring material produced by hot and cold coiling were implemented ...

Nanostructuring steel for injection molding tools
Journal of Micromechanics and Microengineering, 2014The production of nanostructured plastic items by injection molding with ridges down to 400 nm in width, which is the smallest line width replicated from nanostructured steel shims, is presented. Here we detail a micro-fabrication method where electron beam lithography, nano-imprint lithography and ion beam etching are combined to nanostructure the ...

Recrystallization in Nanostructured Austenitic Stainless Steel
Materials Science Forum, 2008Recrystallization and grain growth were studied in an austenitic stainless steel 316LVM processed by hydrostatic extrusion (HE) to a total true strain of 2. HE processing produces in this material the microstructure which consists of nanoscale twins on average 19 nm in width and 168 nm in length.
