Journal ArticleDOI
Mechanistic Studies in Friction and Wear of Bulk Materials
TL;DR: In this article, a review of recent contributions from recent experimental investigations of three classes of materials that exhibit uniquely contrasting tribological behaviors: metals, polymers, and ionic solids is presented.
Journal ArticleDOI
Grain boundary segregation in immiscible nanocrystalline alloys
TL;DR: Based on a diffuse interface model, this paper examined grain growth dynamics in immiscible nanocrystalline (NC) alloys, where both grain boundary (GB) solute segregation and bulk phase separation act in conjunction.
Journal ArticleDOI
Impact of Microstructure on MoS2 Oxidation and Friction
John F. Curry,Mark Wilson,Henry S. Luftman,Nicholas C. Strandwitz,Nicolas Argibay,Michael Chandross,Mark A. Sidebottom,Brandon A. Krick +7 more
TL;DR: Investigation of oxidation and friction for two MoS2 films with distinctively different microstructures-amorphous and planar/highly-ordered- before and after exposure to atomic oxygen (AO) and high-temperature (250 °C) molecular oxygen shows comparable oxidation of both coatings via AO; however, monolayer resolved compositional depth profiles from HS-LEIS reveal that the microstructure of the ordered coatings limits oxidation to the first atomic layer.
Journal ArticleDOI
Mechanical and Corrosion Properties of Additively Manufactured CoCrFeMnNi High Entropy Alloy
Michael A. Melia,Jay Carroll,Shaun R. Whetten,Saba Navabzadeh Esmaeely,Jenifer S. (Warner) Locke,Emma M. H. White,Iver E. Anderson,Michael Chandross,Joseph R. Michael,Nicolas Argibay,Eric J. Schindelholz,Andrew B. Kustas +11 more
TL;DR: In this article, the authors investigated the mechanical and corrosion properties of as-built and annealed equiatomic CoCrFeMnNi alloy produced by laser-based directed energy deposition (DED) additive manufacturing.
Journal ArticleDOI
High-throughput additive manufacturing and characterization of refractory high entropy alloys
Michael A. Melia,Shaun R. Whetten,Raymond Puckett,Morgan R. Jones,Michael Heiden,Nicolas Argibay,Andrew B. Kustas +6 more
TL;DR: In this article, a high-throughput alloy processing and characterization methodology, leveraging laser-based metal additive manufacturing (AM) and mechanical testing techniques, is presented to enable rapid exploration of RHEAs/RCCAs.
