Duplex Stainless Steel Laser‐Surface Textured: Stability in Brine Solution

Advanced Engineering Materials, EarlyView.
Controlled laser‐surface treatment (LST) of duplex DSS2205 steel is performed to increase its stability in brine solution under cyclic electrochemical assays. The superior protection with respect to flat and smooth panels is attributed to the presence of FeCr2O4 as the main protective oxide layer in the LST surface, after corrosion tests. The stability

Ground behaviour analysis, support system design and construction strategies in deep hard rock mining – Justified in Western Australian's mines

Journal of Rock Mechanics and Geotechnical Engineering, 2020
Development of deep underground mining projects is crucial for optimum extraction of mineral deposits. The main challenges at great depth are high rock stress levels, seismic events, large-scale deformation, sudden failures and high temperatures that may

Hund's Rule for Composite Fermions

, 1993
We consider the ``fractional quantum Hall atom" in the vanishing Zeeman energy limit, and investigate the validity of Hund's maximum-spin rule for interacting electrons in various Landau levels.

Interactions between Molten High‐Silicon Electrical Steels and Carbon‐Bonded MgO Refractories Based on Recyclates

Advanced Engineering Materials, EarlyView.
This study examines how several molten high‐silicon electrical steels interact with both conventional and recycled MgO–C refractories. For this, various immersion experiments are conducted. In addition to infiltration, a number of mechanisms are identified and explained that control the corrosion of the refractory material.

Mapping near-surface S-wave attenuation in the onshore southeastern flank of the Red Sea Rifting system in Saudi Arabia

Geomatics, Natural Hazards & Risk
This study aims to quantify the site attenuation parameter, kappa (κ), in the southeastern flank of the Red Sea rifting system. To determine κ, a least-squares best-fit method was applied to three-component seismograms, allowing for the modelling of the ...

Laser Metal Deposition of Aluminum Alloys 7075 and 5083 with the Addition of Volatile Alloying Elements through Powder Blending

Advanced Engineering Materials, EarlyView.
This study investigates laser metal deposition of aluminum alloys EN AW‐7075 and EN AW‐5083, using powder blending to compensate zinc and magnesium evaporation. In situ alloying and ex situ alloying with ZnAl12 and AZ91 preserve near‐standard compositions and improve mechanical properties.
