Mitigating Creep Anisotropy and Enhancing Performance in Additively Manufactured Ni‐Based Superalloys: A Review

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing introduces pronounced microstructural and crystallographic anisotropy in Ni‐based superalloys, resulting in orientation‐dependent creep deformation and damage. This review identifies the key microstructural origins of creep anisotropy, examines their influence on dominant deformation mechanisms, and highlights processing ...

On the effect of pre-oxidation on the nitriding kinetics

open access: yes, 2000
The oxidation of ferritic surfaces prior to gaseous nitriding has been reported to lead to improved uniformity of the compound layer thickness and enhanced nitriding kinetics. The present work considers the nucleation and growth of a model compound layer

Electrodeposition in Structural Lattices of Variable Architectures

open access: yesAdvanced Engineering Materials, EarlyView.
Electrodeposition enables geometry‐sensitive, autonomous void filling while simultaneously tuning chemical and mechanical properties. The development of approaches that can autonomously fill and heal material voids and yield composites with tailorable properties is increasingly relevant in engineering.

Digital Light Processing of Thermoplastic Poly(methyl methacrylate) Photoresin Combined With Solvent Vapor Smoothing

open access: yesAdvanced Engineering Materials, EarlyView.
A thermoplastic PMMA‐based photoresin enables high‐resolution DLP printing followed by solvent‐vapor smoothing. The treatment reduces staircase‐induced surface roughness from 2.33 µm to 129 nm and increases visible‐light transmittance from approximately 30% to 80%, providing a route toward transparent PMMA components for rapid prototyping and non ...

Upcycled MgO–C recyclates as carbon-free anodes for primary aluminum production: effect of pre-oxidation treatments on corrosion resistance to cryolitic melts evaluated by hot-stage microscopy at 1000°C

open access: yesOpen Ceramics
The effect of thermal pre-oxidation on the microstructure and molten-salt interaction of MgO–316L composite anodes produced from decarbonized MgO–C refractory recyclate was investigated. Composite anodes containing 40 vol.% recycled MgO and 60 vol.% AISI

Pre-growth dependent phenotypes for P. aeruginosa nitrate reductase mutants.

open access: yes
Left: When cultures were pre-grown in slanted shaking tubes, providing the cultures ample oxygen, only the ΔnapAB strain (orange) had a PCA oxidation deficit. Right: Pre-growing the cultures in standing tubes without nitrate supplementation also leads to

Adjusting Nucleation Chemistry for the Atomic Layer Deposition of Antimony Selenide on Metal Oxide Surfaces

open access: yesAdvanced Engineering Materials, EarlyView.
The ALD precursor bis(trimethylsilyl)selenide is simultaneously a substrate surface inhibitor. It allows for the growth of Sb2Se3 in combination with tris(dimethylamido)antimony, but also silylates surface hydroxyl groups on the substrate if such hydroxyls are present.

Atmospheric alkaline pre-oxidation of refractory sulphide gold ores

open access: yes, 2018
Four iron-sulphide-containing gold ores from the White Mountain mine in the Jilin Province, China were studied to examine the benefits of using oxidative treatment prior to conventional cyanidation to leach gold.
