Microstructure- and Texture Design of Nonferrous Metals
Mechanical properties and the formability of metallic materials are influenced by the alloy composition but also significantly by microstructure and texture. Therefore, design of these properties in order to optimize the formability already starts during the solidification. Nevertheless, variation of deformation and heat treatment parameters is what exerts the strongest effect on the final microstructure and texture.
Design and modification of Al-Mg-Si-alloys
Lightweight construction is the dominant theme in the automotive and aerospace industries, especially in the development of new models. Due to the advantageous properties of aluminum alloys, such as a low density combined with high strength, there is enormous potential to realize significant weight savings. However, what limits even more extensive use of aluminum in these areas is insufficient strength or formability.
Cross-class design approach for new aluminum alloys - INTERMIXING
The low density and the resulting potential for lightweight structural applications have already put aluminum and its alloys into the focus of automobile manufacturers for quite some time.
Optimization of AlMgMn- and AlMgSi-alloys for cryogenic deformation
In recent years the automotive industry focuses on the application of high-strength 5xxx and 6xxx alloys. In order to achieve sufficient plasticity and good surface qualities deep drawing processes are carried out at cryogenic temperatures.
Texture- and microstructure-engineering of aluminium alloys
The ever-increasing demands in the aluminium industry with regard to the mechanical characteristics and the deformation behaviour of different alloys require a profound analysis of the different influencing factors. In addition to studies of the influence on the material from the process control, attention is also paid to the texture development (= entirety of the orientations of the grains).
Optimized AlMgMn alloys for complex forming applications in the automotive industry
In order to meet the increasingly stringent emission standards, lightweight construction has made headway across the automotive industry. Aluminum alloys are therefore used for a wide variety of applications. AlMgMn alloys have been a particular focus in recent years for opening up new application possibilities and providing a cost-efficient alternative to AlMgSi sheets. Since the deformation of AlMgMn sheets at room temperatures usually leads to undesirable surface effects, measures must be taken to make them suitable for decorative components such as automotive outer panels.
