Hydrogen Analyses of FSW Cu‐OFP Tested Under Creep Conditions in Sulphide Containing Environment

Materials and Corrosion, EarlyView.
Friction stir welded Cu‐OFP exhibits elevated creep rates in sulphide‐containing aqueous environments, with creep increasing as sulphide concentration rises. Hydrogen measurements indicate that sulphide exposure does not increase hydrogen content. ABSTRACT Friction stir welded oxygen‐free phosphorus‐doped copper (FSW Cu‐OFP) is a candidate material for

Multi-objective optimization of the process combining ultrasonic vibration and age-forming of dissimilar friction-stir-welded Aluminium T-stiffened plates

Manufacturing Review
This paper innovatively proposes a combined process combining ultrasonic vibration (abbreviated UV) with creep age forming (abbreviated CAF), named UVCAF, for high-quality forming of dissimilar 7055-T6/2197-T8 FSWed T-stiffened plates. And based on this,

Nonprofit Governance and Financial Stability: A Study of Government‐Funded Social Services

Nonprofit Management and Leadership, EarlyView.
ABSTRACT Nonprofit social service providers are essential in delivering vital services, often with public funding. This study adopts a contingency perspective to explore the relationship between organizational governance and financial stability in publicly funded nonprofit organizations. We use a combination of comparative multilevel analysis (CMA) and

Application aux pièces en alliages d’aluminium moulés [PDF]

, 2009
Le soudage par friction malaxage (FSW) est un procédé de soudage de proche en proche à l’état solide. Ceci permet d’éviter la formation de certains défauts apparaissant lors de la solidification en soudage par fusion comme les fissures à chaud ou les ...

Zero‐Current Switching Based Model Predictive Control of a Double‐Extended Overlapped Alternate Arm Converter Used in the VSC–HVDC System

High Voltage, EarlyView.
ABSTRACT The alternate arm converter (AAC) is one of the most efficient multilevel topologies based on voltage source converters (VSCs), which has recently gained attention in various applications, particularly in high voltage direct current (HVDC) systems.

The Effect of Friction Stir Welding Parameters on the Weldability of Aluminum Alloys with Similar and Dissimilar Metals: Review

Metals, 2022
The solid-state welding method known as friction stir welding (FSW) bonds two metallic work parts, whether the same or different, by plastically deforming the base metal.

Three More Poecilogonous Sacoglossans: Why Is Egg‐Size Dimorphism Generally Rare Except in One Lineage of Sea Slugs?

Integrative Zoology, EarlyView.
We report three additional species of sea slugs that express poecilogony, or egg‐size dimorphism, a form of life‐history plasticity that occurs about 200 times more often in clade Sacoglossa than in other marine gastropod groups. We present evidence that poecilogony permits local adaptation to ocean productivity and circulation, given the alternative ...
