Initial characterisation of mechanical and corrosion properties of stationary shoulder friction stir welded bare and Alclad AA2024-T3 butt joints

Aluminium alloy AA2024-T3 is a lightweight and damage tolerant material, and is therefore often used in aerospace applications. However, this alloy is difficult to weld using conventional fusion welding techniques due to defects caused by the meld pool.<br/> <br/>Friction stir welding (FSW) was developed by The Welding Institute (TWI) in 1991 in...

Predicting the Pit-to-Crack Transition of Offshore Wind Turbine Foundations: A mechanistic determination

Offshore wind turbines are designed to persist harsh environmental conditions, including corrosion. Pitting corrosion is one of the most dangerous forms of corrosion. In combination with a fatigue loading, a corrosion pit could result into the failure of a structure, due to a minimal weight reduction. Of the corrosion fatigue process, the...
