The use of aluminum alloys with a high strength in conjunction thermal-assisted forming techniques permits the production high-strength and geometrical complicated components without failure. Due to temperature-dependent material behavior, it is achievable modify mechanical properties during forming. Hence, tailored feasible. Currently, determination microstructural characteristics challenge for design innovative process routes due temperature, stress time dependence these materials. Till...
The use of high‐strength aluminum components in automotive manufacturing offers the opportunity to reduce vehicle weight significantly and provide new lightweight potentials. In past, so‐called hot forming quench process (HFQ) successfully demonstrates potential for production complex‐shaped made out age‐hardenable alloys. Currently, no method permits wear‐free without lubricants. To fulfill increasing ecological economic requirements, it is necessary identify wear‐reducing techniques...
Abstract High-strength aluminum alloys are more and used for safety crash-relevant components due to their advantageous density-to-strength ratio. By using thermal-supported forming strategies, failure-free deep drawing is possible these materials. In this context, the hot form quench process (HFQ ® ) has shown be a promising thermally-assisted strategy. locally tempered tools, production of tailored with different mechanical properties possible. However, material characterization design...
High-strength aluminum alloys have a great lightweight potential due to their high specific strength-to-weight ratio. However, industrial use of this material is limited the low formability at room temperature. In recent years, so-called hot forming quench (HFQ ® ) process has proven, be an effective method for manufacturing high-strength alloys. During deep drawing, cooling rate generates subsequent aging operation and thereby formation strength-increasing precipitations. As result,...
Abstract In the field of mobility, increased safety and emission requirements lead to steadily rising demands on materials used their performance. Over last decades, 5000 6000 series aluminum alloys have become more attractive as lightweight material due beneficial weight strength ratio. The 7000 offers extended potential its high strength. Until now, this class has not been widely in mass production limited corrosion resistance poor forming behavior. By using so-called Tailor Heat Treated...
Nowadays, fuel-efficient vehicles with high safety standards are required in the automotive industry. Lightweight materials like aluminum alloys play an important role for this development because of their specific strength and low density. However, application is still restricted due to limited formability at temperatures. By use thermal supported forming processes, complex part geometries can be realized. Nevertheless, adhesion tendency heated lack manufacturing-friendly...
Abstract High-strength aluminum alloys of the 7XXX series have a high potential for safety and crash-relevant components due to their advantageous density-to-strength ratio. Currently, use these is limited because low formability at room temperature. By using thermal supported forming strategies, failure-free deep drawing possible materials. At present, several thermal-assisted processes exist, but so far there no comparison between operations. For this purpose, study compares behavior alloy...

The combination high-strength aluminum alloys thermal-assisted forming operations an innovative method for production varying mechanical properties. By locally adjusting cooling rates during a thermo-mechanical operation, it possible to modify microstructure precipitation conditions. A subsequent aging operation causes...
Aluminum alloys fulfill the growing demands for lightweight applications and are completely recyclable. The use of high-strength aluminum offers opportunity to replace safety-relevant steel components. Currently, these is limited due their low formability high springback during forming at room temperature. tailored blanks with locally adapted material properties one overcome limitations. By local heat treatment, zones softened thus crack critical areas can be avoided. At present, not used...
High-strength aluminum alloys provide great potential for weight reduction in vehicle and aircraft production. Nevertheless, forming of these materials is limited at room temperature. Thermally supported operations such as hot quenching (HFQ ® ) allow components without failure reduced springback. Currently, the adhesive wear high friction limit use HFQ -operations high-strength alloys. Out this reason, present paper describes tribological performance new developed dry lubricants elevated...

Abstract In order to cope with the upcoming challenges from industrial trends, such as mass customization, hybrid parts made out of sheet metal and additively manufactured components offer a possible approach. Hybrid can be used for instance in field medical aerospace industries. The combination two technologies forming additive manufacturing allows use advantages each while at same time avoiding disadvantages. During process, however, substrates, which are component later part, subjected...
The use of high-strength aluminum alloys in combination with thermal-assisted forming techniques permits the failure-free production and geometrical complicated components.
