The special collection focuses on recent advances in the science and technologies associated with aluminium, magnesium and titanium alloys. Topics span the full light metals field from the development of new alloys, through processing and material behaviour, to final application, and increasingly the issues of sustainability and end-of-life. The papers are arranged in the following chapters: 1. Alloy Development; 2. Casting & Solidification; 3. Forming; 4. Heat Treatment & Phase Transformations; 5. Mechanical Behaviour, 6. Corrosion & Surface Modification; 7. Joining; and 8. Applications. This volume provides a snapshot of the current status and trends in light metals research, and will be an invaluable resource for readers in academia and industry alike.
