Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

Advanced Engineering Materials, EarlyView.
Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Distinct Microstructural Characteristic Lengths Defining Notch Fatigue Crack Initiation and Propagation, and Defect Tolerance in Advanced Steels

Advanced Engineering Materials, EarlyView.
Schematic representation of modes of microcrack nucleation, growth and temporary arrestment at different boundaries, with the criteria for crack propagation in three scenarios: (1) large notch, (2) defect/small sharp notch, and (3) long crack. This work revisits and integrates results on the fatigue behavior of advanced bainitic steels (in particular ...

The Dependency of Bar Formation Timescale on Disk Mass Fraction, Toomre Q, and Scale Height

The Astrophysical Journal
Bars are one of the most prominent galactic structures. The classical swing-amplification theory can qualitatively describe the spontaneous bar instability of stellar disks.

MOCCA code for star cluster simulations - ii. comparison with n-body simulations

, 2013
We describe a major upgrade of a Monte Carlo code that has previously been used for many studies of dense star clusters.We outline the steps needed in order to calibrate the results of the newMonte Carlo code against N-body simulations for large-N ...

N-Body Simulations on Massively Parallel Architectures

Journal of Computational Physics, 1994
The simulations of the properties of \(N\) particles, mutually interacting through a pair-wise force, yield information that is inaccessible by other means and that leads to insight into predictable behavior for a wide range of problems. In this paper, the authors give several simple procedures that reduce by an order of magnitude the computation time ...

Accretion History Dependence of the Halo Depletion Radius

The Astrophysical Journal
We investigate the role of the accretion history in shaping the depletion radius of dark matter halos using a large cosmological N -body simulation. We show that the inner depletion radius, rescaled by the virial radius, depends strongly on the recent ...

Discrepancies Between Micro Versus Macroscale Viscoelastic Properties in a Microplastic‐Tissue Composite Model

Advanced Engineering Materials, EarlyView.
This study explores the discrepancies between bulk mechanics and spatial mapping in a tissue‐mimetic hydrogel model. Microplastic particles create localized stiff mechanical microenvironments that are detectable by cellular‐scale nanoindentation but leave bulk properties unchanged as measured by rheology.
