Title: Complex Nano-Scale Structures for Unprecedented Properties in Steels

Abstract

Processing bulk nanoscrystalline materials for structural applications still poses a rather large challenge, particularly in achieving an industrially viable process. In this context, recent work has proved that complex nanoscale steel structures can be formed by solid reaction at low temperatures. These nanocrystalline bainitic steels present the highest strength ever recorded, unprecedented ductility, fatigue on par with commercial bearing steels and exceptional rolling-sliding wear performances. In this paper, a description of the characteristics and significance of these remarkable structures in the context of the atomic mechanism of transformation is provided.

Modern steels at atomic and nanometre scales

Journal Article Caballero, F. G. ; Garcia-Mateo, C. ; Miller, M. K. - Materials Science and Technology

Processing bulk nanocrystalline materials for structural applications still poses a difficult challenge, particularly in achieving an industrially viable process. Recent work in ferritic steels has proved that it is possible to move from ultrafine to nanoscale by exploiting the bainite reaction without the use of severe deformation, rapid heat treatment or mechanical processing. This new generation of steels has been designed in which transformation at low temperature leads to a nanoscale structure consisting of extremely fine, 20–40 nm thick plates of bainitic ferrite and films of retained austenite. Finally, a description of the characteristics and significance of this remarkable microstructuremore » is provided here.« less

Low Temperature Surface Carburization of Stainless Steels

Technical Report Collins, Sunniva R ; Heuer, Arthur H ; Sikka, Vinod K

Low-temperature colossal supersaturation (LTCSS) is a novel surface hardening method for carburization of austenitic stainless steels (SS) without the precipitation of carbides. The formation of carbides is kinetically suppressed, enabling extremely high or colossal carbon supersaturation. As a result, surface carbon concentrations in excess of 12 at. % are routinely achieved. This treatment increases the surface hardness by a factor of four to five, improving resistance to wear, corrosion, and fatigue, with significant retained ductility. LTCSS is a diffusional surface hardening process that provides a uniform and conformal hardened gradient surface with no risk of delamination or peeling. The treatmentmore »« less

Rolling-contact and wear resistance of hard coatings on bearing-steel substrates

Conference Erdemir, A

Ever-increasing needs for high-performance ball- and roller-bearing components that can endure extreme applications have led to a growing interest in hard coatings for improved fatigue life and wear resistance. In particular, hard TiN and TiC coatings and, quite recently, diamond like carbon films have attracted much attention from manufacturers that produce bearing systems for both rolling- and sliding-contact applications. This paper presents an overview that highlights recent incremental progress in achieving improved fatigue and wear resistance in bearing steels through the use of hard coatings. Effects of coating adhesion, thickness, and morphology on fatigue and wear resistance of hard coatingsmore »« less

Tribological properties of reactively sputtered nitrides and carbides of titanium, zirconium and hafnium. Final report

Technical Report Graham, M E ; Chang, P ; Sproul, W D

Objective was to determine the tribological properties of hard, wear-resistant coatings on steel substrates in order to expedite their use on coated roller bearings, transmission gears, cams, etc. Specific coatings investigated were TiN, TiC, ZrN, ZrC, HfN, and HfC; they were deposited by high-rate-reactive magnetron sputtering. Both nitrides and carbides improved the wear performance of steel, often by orders of magnitude. These coatings have proven to be beneficial for dry sliding, lubricated sliding, rolling, and mixed rolling/sliding wear. The rolling contact fatigue studies showed remarkable improvements of lifetime that could be achieved with very thin coatings (less than one micron);more »« less
