Radiation resistant Al alloys for space applications

Project monitoring: Dipl.-Ing. Patrick WillenshoferUniv.-Prof. Dipl.-Ing. Dr.mont. Stefan Pogatscher In order to reduce CO2 emissions, aluminum and its alloys are increasingly in the focus of attention in lightweight automotive construction. To improve the recyclability of aluminum, so-called “crossover alloys” have been developed. By mixing AlMg (5xxx) with AlZnMg (7xxx) alloy classes, the novel alloys are […]

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

Project monitoring: Dipl.-Ing. Bernhard TrinkUniv.-Prof. Dipl.-Ing. Dr.mont. Stefan Pogatscher 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. In aluminum alloys it tends to […]

Optimization and industrial establishment of aluminum crossover alloys

Project monitoring: Dipl.-Ing. Sebastian SambergerUniv.-Prof. Dipl.-Ing. Dr.mont. Stefan Pogatscher 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 […]

In situ Transmission Electron Microscopy (TEM)

Project monitoring: Diego Santa Rosa Coradini, MScUniv.-Prof. Dipl.-Ing. Dr.mont. Stefan Pogatscher In situ TEM heating is a tool that aims at the analyses of very localized transformations while undertaking the environment under different thermodynamical conditions by modifying its temperature. The in situ heating is done by a microelectron mechanical system (MEMS), in our case small […]

Influence of the input material on the melt quality of aluminium alloys

Project Managers: Dipl.-Ing. Thomas Doppler Univ.-Prof. Dipl.-Ing. Dr.mont. Helmut Antrekowitsch The source and formation of specific non-metallic inclusions in aluminium alloy melts are of major interest. For the investigations, an AlMg5-melt, based on different input material, is produced in a resistance furnace. Furthermore the melt is contacted with refractory material. The determination of type and […]
