Precipitation hardenable aluminum alloys currently belong to the most important lightweight materials. For this reason, they are applied in many fields of day-to-day life. But for most products - from smartphones to airplanes like the Airbus A380 - the limited formability is still an unsolved challenge. Therefore, within this fundamental research project a new and innovative technique to improve formability of precipitation hadenable aluminum alloys was developed. Through the patented technology of Tailor Quenched Blanks, it’s possible to achieve mechanical properties which are stress optimized for a required application, by applying a locally tailored quenching velocity after solution heat treatment. The holistic understanding of the underlying principles will make an important contribution in order to fulfil customers quality and individuality demands in an resource and environmental friendly way.
