To cover the energy supply with renewable energies is a challenge of local and temporal distribution of renewable sources that requires energy storage technologies. Complex hydrides, which contain ions such as BH4- and NH2-, have a high hydrogen capacity and therefore are candidates for solid state hydrogen storage materials. Many studies reported the improvement of hydrogen reaction in...

The polycrystalline Co-base superalloy CoWAlloy1 provides a high potential for high temperature applications as wrought alloy due to a high $\gamma$' precipitate fraction and $\gamma$/$\gamma$' lattice misfit which lead to excellent creep properties. However, cracking occurs during hot rolling. Therefore, this study investigated the origins of crack formation during processing.

Magnesium alloys have the advantages of low density, high specific strength and specific stiffness, so they have been widely used in many fields, such as aerospace, aerospace, automobile and electronic products, etc [1,2]. However, the application of magnesium alloys is limited because of the low modulus, low strength and poor plasticity at room temperature. In recent years, it has been found...

Process-induced residual stresses (RS), which are induced as a result of plastic deformation, can lead to plastic anisotropy effects caused by intergranular strains. The strict application of diffraction elastic constants (DEC) to calculate phase-specific RS, as tabulated for many material phases in literature, can lead to arguably erroneous RS calculations. These plastic anisotropy effects...

The goal of the BMBF funded project HiMat is the optimization of an innovative testing machine to perform deformation experiments at high temperatures at various instruments at the research neutron source Heinz Maier-Leibnitz. With diffraction, small-angle scattering and radiography (tomography) it is possible to investigate forming phases, their volume fractions as well as size and shape,...

Metal Additive manufacturing (AM) technologies such as Laser Powder Bed Fusion (LPBF) enable the fabrication of complex structures, giving rise to potential improvements in component and manufacturing efficiency. However, the processes are typically characterized by the generation of high magnitude residual stresses which can have detrimental consequences for subsequent applications....

CuTi-based glass forming alloys feature a large undercooled liquid region and a high glass-forming ability, which makes them interesting materials particularly for biomedical and lightweight applications. However, for the development of alloy compositions with optimized glass-forming abilities, the relevant mechanisms on the atomic scale are still to be explored. For a fundamental...

Zr based alloys are widely used in nuclear power plants as nuclear fuel cladding. These materials have an excellent combination of mechanical resistance, corrosion resistance and very low neutron absorption. However, they are susceptible to H degradation, following incorporation of H by a slow oxidation process at operating temperatures (~300°C). For long operational service, Zr based...
