Low‐Cost, Large‐Scale Nanoporous Metals by Mechanical Alloying, Oxide Reduction, and Dealloying of Powders

open access: yesAdvanced Engineering Materials, EarlyView.
Powder metal processing provides scalable advantages in nanoporous (np) metal development. Mechanical alloying is used to produce unique precursors for hybrid nanopore formation by oxide reduction and dealloying. As demonstrated in np Ag, this approach improves process efficiency while promoting smaller ligaments and larger pores, both of which are ...

Study on the Corrosion Behaviours of X80 Pipeline Steel Joints Fabricated via Hot-Wire Tungsten Inert Gas Welding

open access: yesInternational Journal of Electrochemical Science, 2019
X80 pipeline steel joints were fabricated via hot-wire tungsten inert gas welding by using ER70S-G wire with a diameter of 1.2 mm. The microstructures of the welded joints were analysed by using metallographic microscopy.

On the Brittleness of Heat-affected Zone (Report 5)

open access: yesJOURNAL OF THE JAPAN WELDING SOCIETY, 1955
It is recognized that the impact-resistance of sharp-notched specimen decreases suddenly at the so-called "transition temperature". Below this temperature the fracture shows more brittle than shear one and at low temperatures the shear fracture vanishes.

Innovative Processing of Compacted Waste Aluminum Alloy Powders via Controlled Remelting and Solidification

open access: yesAdvanced Engineering Materials, EarlyView.
This study demonstrates an efficient recycling route for out‐of‐spec AlSi10Mg atomized powders through compaction and arc remelting followed by suction casting. By correlating compaction load, cooling rate, and resulting microstructure, we show that intermediate pressures (50–80 kN) and rapid cooling refine dendrites, reduce porosity, and enhance ...

Zein‐Based Adhesives: Sustainable Extraction and Application in Bioadhesive Technologies

open access: yesAdvanced Engineering Materials, EarlyView.
Zein is extracted from corn gluten meal using a simple and scalable process with high yield (~90%). The resulting protein is applied in bioadhesives modified with Ca2+ and Fe3+ ions, exhibiting substrate‐dependent adhesion. The findings demonstrate competitive bonding performance and highlight the role of ionic interactions in tuning adhesion ...
