| Abstract Scope |
Over the last decades the evolution of transportation and traffic has significantly challenged the automotive industry due to the negative environmental aspects coming along with these changes. Light-weight construction and increased demand on design flexibility has led to the development of new aluminum-based materials capable of replacing heavy and, therefore, unbeneficial materials and offering new possibilities towards increasing freedom of design.
Progress has been made by the development of 5xxx-series aluminum alloys offering superplastic formability and, therefore, enabling the production of outer car body parts with high demands on formability and complexity. A major drawback of commonly used alloys for such forming operations is their relatively low strength in operation.
This study investigates novel alloy design strategies offering increased strength without negatively affecting the superior formability. Detailed investigations on thermomechanical treatment and microstructure evolution are performed in this study. |
