Cyclic degradation of titanium-tantalum high-temperature shape memory alloys - The role of dislocation activity and chemical decomposition

Niendorf, T.; Krooß, P.; Somsen, C.; Rynko, R.; Paulsen, A.; Batyrshina, E.; Frenzel, J.; Eggeler, Gunther; Maier, Hans Jürgen (Singapore : World Scientific Publishing Co. Pte Ltd, 2015)

Titanium-tantalum shape memory alloys (SMAs) are promising candidates for actuator applications at elevated temperatures. They may even succeed in substituting ternary nickel-titanium high temperature SMAs, which are either ...
Evaluation of the Efficiency of an Elevated Temperature Proton Exchange Membrane Water Electrolysis System

Bonanno, Marco; Müller, Karsten; Bensmann, Boris; Hanke-Rauschenbach, Richard; Peach, Retha; Thiele, Simon (Pennington, NJ : Electrochemical Society, 2021)

In recent years, a significant interest has been growing in elevated temperature (ET) electrolytes for proton exchange membrane water electrolysis (PEMWE). In this study, the energy and exergy analysis developed for PEMWE ...
Experimental Characterization and Material Modelling of an AZ31 Magnesium Sheet Alloy at Elevated Temperatures under Consideration of the Tension-Compression Asymmetry

Behrens, Bernd-Arno; Bouguecha, Anas; Bonk, Christian; Dykiert, M. (Bristol : Institute of Physics Publishing, 2017)

Magnesium sheet alloys have a great potential as a construction material in the aerospace and automotive industry. However, the current state of research regarding temperature dependent material parameters for the description ...
Formability of 7000 aluminum alloys in warm and hot forming condition

Behrens, Bernd-Arno; Hübner, S.; Vogt, H. (Bristol : Institute of Physics Publishing, 2018)

In recent years, the automobile industry has been calling for new lightweight solutions to fulfill increasing ecologically requirements. A weight reduction of automobile body constructions is necessary to reduce fuel ...
In situ spectroscopic ellipsometry as a pathway toward achieving VO2stoichiometry for amorphous vanadium oxide with magnetron sputtering

Xu, C.; Heinemeyer, F.; Dittrich, A.; Bäumer, C.; Reineke-Koch, R. (New York, NY : American Inst. of Physics, 2021)

As a special class of materials, transition metal oxides exhibit in their crystalline phase a variety of interesting properties, such as metal-insulator transition, ferroelectricity, magnetism, superconductivity, and so ...
Microstructural evolution and functional fatigue of a Ti–25Ta high-temperature shape memory alloy

Maier, Hans Jürgen; Karsten, Elvira; Paulsen, Alexander; Langenkämper, Dennis; Decker, Peer; Frenzel, Jan; Somsen, Christoph; Ludwig, Alfred; Eggeler, Gunther; Niendorf, Thomas (Cambridge : Cambridge University Press, 2017)

Titanium–tantalum based alloys can demonstrate a martensitic transformation well above 100 °C, which makes them attractive for shape memory applications at elevated temperatures. In addition, they provide for good workability ...
Numerical and experimental determination of cut-edge after blanking of thin steel sheet of DP1000 within use of stress based damage model

Behrens, Bernd-Arno; Bouguecha, Anas; Vucetic, Milan; Krimm, Richard; Hasselbusch, Tobias; Bonk, Christian (Amsterdam : Elsevier, 2014)

The proposed study focuses on blanking of thin steel sheets of Dogal1000DP +Z100MBO. Numerical and experimental investigations of the influence of clearance and punch speed on the cutting force and the geometry of the ...
Simulation of a flush endplate connection at elevated temperatures including fracture simulation

Schaumann, Peter; Kirsch, Thomas (Bingley : Emerald Group Publishing Ltd., 2013)

Actual developments in numerical simulations of the structural behaviour in fire situation are focussed on taking into consideration the interaction of all structural members in a global numerical approach. Therefore it ...
Understanding the Light-induced Lifetime Degradation and Regeneration in Multicrystalline Silicon

Bredemeier, Dennis; Walter, Dominic; Herlufsen, Sandra; Schmidt, Jan (London : Elsevier Ltd., 2016)

In this contribution, we focus on improving the fundamental understanding of the carrier lifetime degradation and regeneration observed in block-cast multicrystalline silicon (mc-Si) wafers under illumination at elevated ...
