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 […]
Influence of cluster hardening on strength and strain hardening behavior of various aluminum alloys
Project monitoring: Dipl.-Ing. Philip AsterUniv.-Prof. Dipl.-Ing. Dr.mont. Stefan Pogatscher 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 […]
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 […]
