The Effect of Steel Electropolishing on the Tribological Behavior of a Steel–Bronze Pair in the Mixed and Boundary Lubrication Regimes

open access: yesLubricants, 2023
Electropolishing at high current densities without agitation of the electrolyte results in a pitting phenomenon that produces dimple-like surface features.

Epitaxial growth of hexagonal tungsten bronze CsxWO3 films in superconducting phase region exceeding bulk limit [PDF]

open access: yesAppl. Phys. Express 9, 075801 (2016), 2016
We report epitaxial synthesis of superconducting CsxWO3 (x = 0.11, 0.20, 0.31) films on Y-stabilized ZrO2 (111) substrates. The hexagonal crystal structure was verified not only for composition within the stable region of bulk (x = 0.20, 0.31), but also for the out-of-range composition (x = 0.11). The onset of superconducting transition temperature (TC)

An Examination of Aerosol Jet‐Printed Surface Roughness and its Impact on the Performance of High‐Frequency Electronics

open access: yesAdvanced Engineering Materials, EarlyView.
This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave

Microstructure, Mechanical Properties, and Antibacterial Performance of Novel Fe‐Mn‐Zn Nanocrystalline Alloys Produced by Mechanical Alloying

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents the development of Fe‐Mn‐Zn nanocrystalline alloys (0–9 wt% Zn) by mechanical alloying and subsequently hot pressing. Their microstructure, density, hardness, wear resistance, corrosion behavior, and antibacterial properties are systematically examined.

Static Recrystallization Simulation of Interstitial Free‐Steel by Coupling Multi‐Phase‐Field and Crystal Plasticity Model Considering Dislocation Density Distribution

open access: yesAdvanced Engineering Materials, EarlyView.
This study models static recrystallization in interstitial free‐steel using coupled crystal plasticity and phase‐field simulations. The method directly links heterogeneous dislocation density to nucleation site prediction, eliminating reliance on empirical assumptions.
