Journal ArticleDOI
Effect of Environment on Microstructure Evolution and Friction of Au–Ni Multilayers
Ebru Cihan,Katherine L. Jungjohann,Nicolas Argibay,Michael Chandross,Martin Dienwiebel,Martin Dienwiebel +5 more
TL;DR: In this paper, Cihan et al. present results from a systematic investigation of environmental effects on the frictional behavior of Au-Ni multilayer films of varying interlayer spacing.
Journal ArticleDOI
Additive manufacturing of high-strength multiphase nanostructures in the binary Ni–Nb system for the discovery of new types of superalloys
Morgan R. Jones,Frank W. DelRio,Jonathan Pegues,Ping Lu,Raymond Puckett,N. S. Bobbitt,T. J. Hardin,Michael Chandross,Andrew B. Kustas,Nicolas Argibay +9 more
TL;DR: In this paper, the additive manufacturing-enabled investigations of composition-dependent mechanical and micro-structural properties for Ni-Nb binary alloys are presented, where the authors report on the mechanical behavior of compositionally-graded NixNb1−x and uniform composition Ni59.5Nb40.5 specimens made with AM.
Journal ArticleDOI
Friction of Metals: A Review of Microstructural Evolution and Nanoscale Phenomena in Shearing Contacts
TL;DR: In this article, the authors examined the links between mechanisms of strengthening, deformation, and the wide range of friction behaviors that are exhibited by shearing metal interfaces and found that grain boundary sliding and the breakdown of Hall-Petch strengthening at the shearing interface are generally and predictably explain the low friction of these materials.
Patent
Wear-Resistant Nanocrystalline Hard Noble Metal Coating
TL;DR: In this article, a new class of electrically conductive, wear resistant, and high thermal stability nanocrystalline noble metal coatings achieved by codeposition of an insoluble, unreactive, and thermally stable, grain boundary segregated ceramic species that strengthened the base metal by inhibiting grain boundary mobility and recrystallization during deposition.
Journal ArticleDOI
Mechanochemically driven formation of protective carbon films from ethanol environment
A. B. Shirani,Yang Liu,J. Smith,John F. Curry,Ping Lu,Micheal A. Wilson,Michael Chandross,Nicolas Argibay,Doris Berman +8 more
TL;DR: In this article , the effect of temperature and contact pressure on film formation on Pt-Au alloys during sliding in an ethanol environment has been demonstrated by Raman and Transmission Electron Microscopy (TEM) analyses.
