Optimization and industrial establishment of aluminum crossover alloys

The use of conventional wrought aluminium alloys, especially in the automotive industry, always requires a compromise between required strength and sufficient formability. By using aluminium crossover alloys, it is possible to avoid this trade-off, as these alloys offer both high strength and excellent plastic deformability and are therefore more than capable of meeting the industrial requirements of future lightweight construction applications.

Influence of cluster hardening on strength and strain hardening behavior of various aluminum alloys

The low density, wide strength spectrum and extensive application of forming and working processes are just some of the reasons why aluminum alloys are used in so many areas. In addition, minimizing energy consumption is a driving force for the use of lightweight materials such as aluminum. The ongoing conflict in the automotive industry between achieving maximum strength while maintaining high formability has led to an ever-improving understanding of the precipitation sequences of age-hardenable 6xxx and 7xxx series aluminum alloys.

Al-Mg-Si alloys with content of Fe-containing primary phases

One of the biggest challenges in recycling aluminum is the highly diverse composition of aluminum scrap. Iron in particular poses a problem, as it gradually accumulates through the recycling of secondary aluminum and is difficult to remove by metallurgical means.

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.

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.
