Nanostructure Formation in Austenitic Stainless Steel

Solid State Phenomena, 2008
Samples of 316LVM stainless steels were hydrostatically extruded in a multi-step process to a total true strain of 1,84 and subsequently annealed at different temperatures. The structural changes occurring as a result of HE and annealing were observed using a transmission electron microscope.

Mechanical properties of nanostructured bainitic steels

Materialia, 2021
Abstract 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.

Development of nanostructured steel for engineering application

International Journal of Nano and Biomaterials, 2014
The 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.

Nanostructural Engineering of TMCP Steels

2011
This 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, 2016
The 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 ...

Hydrogen-Trapping Mechanisms in Nanostructured Steels

Metallurgical and Materials Transactions A, 2013
Nanoprecipitation-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, 2015
Abstract 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, 2007
The 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).

Nanostructuring steel for injection molding tools

Journal of Micromechanics and Microengineering, 2014
The 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 ...
