Characterization of Hydrogen Storage Materials and Systems with Photons and Neutrons
(2011)
Complex hydrides are very promising candidates for future light-weight solid state hydrogen storage materials. The present work illustrates detailed characterization of such novel hydride materials on different size scales ...
Fabrication of reprogrammable shape-memory polymer actuators for robotics
(2018)
Shape-memory polymer actuators, whose actuation geometry and switching temperatures are reprogrammable by physical fabrication schemes, were recently suggested for robotics with the option for self-healing and degradability.
Operando reaction cell for high energy surface sensitive x-ray diffraction and reflectometry
(2022)
A proof of concept is shown for the design of a high pressure heterogeneous catalysis reaction cell suitable for surface sensitive x-ray diffraction and x-ray reflectometry over planar samples using high energy synchrotron ...
Formation of Intermetallic Compounds in Dissimilar Friction Spot Weld of Al to Mg Alloys
(2013)
In the present study, friction spot welding has been used for joining dissimilar AA5754 aluminum to AZ31 magnesium alloys. To get more insight into the microstructure, stop-action experimentation was employed. The welding ...
The Influence of a Small Boron Addition on the Microstructure and Mechanical Properties of Ti-6Al-4V Fabricated by Metal Injection Moulding
(2011)
The effect of boron additions on the sintering behavior, microstructural development, and mechanical properties of a Ti-6Al-4V alloy fabricated by metal injection moulding (MIM) was studied. The addition of boron promotes ...
Understanding solid solution strengthening at elevated temperatures in a creep-resistant Mg–Gd–Ca alloy
(2019)
The present work studies the strengthening mechanisms of a creep-resistant Mg-0.5Gd-1.2Ca (at.%) alloy at both room and elevated temperatures. Although peak-ageing (T6) at 180 °C for 32 h led to a significant increase in ...
On the thermomechanical coupling in finite strain plasticity theory with non-linear kinematic hardening by means of incremental energy minimization
(2011)
The thermomechanical coupling in finite strain plasticity theory with non-linear kinematic hardening is analyzed within the present paper. This coupling is of utmost importance in many applications, e.g., in those showing ...
Mechanical and Corrosion Properties of Binary Mg-Dy Alloys for Medical Application
(2011)
Microstructure, mechanical and corrosion properties of binary magnesium–dysprosium (Mg-5, 10, 15, 20 wt.% Dy) alloys were investigated for medical applications. In the as-cast condition, the distribution of Dy is quite ...
Development of computational models to predict the mechanical behavior of Friction Riveting joints
(2012)
Friction Riveting (FricRiveting) is a new, friction based, spot joining process for polymer–metal hybrid structures that has been studied experimentally in recent years. The process provides a cost effective and fast ...
Creep properties of different Gamma'-strengthened Co-base superalloys
(2012)
The influence of various alloying elements on the creep properties of polycrystalline Co-base superalloys hardened by a ternary L12 compound, Co3(Al,W) (γ′-phase), was investigated. A Ti containing quaternary alloy shows ...
