The additively manufactured AlSi10Mg alloy demonstrates considerable residual stresses,adversely affecting the dimensional accuracy, operational safety, and corrosion resistance of the parts. Inpractical applications, stress relief annealing is necessary to eliminate residual stresses in residual stress-sensitive applications. [...]

Residual stresses are considered critical to quality in conventional manufacturing strategies. This is where the DFG's Priority Program 2013 comes in, looking instead at the opportunities and possibilities for improving the properties of components by targeted use of residual stresses [...]

Neutron radiation is widely used for investigation of matter at research reactors and spallation sources. One undesired side-effect is the production of radioactive nuclides in structure materials of the instruments (e.g. [...]

Nanopowders of the magnetite–maghemite series have been synthesized by coprecipitation from aqueous solutions and by the sol–gel method, and a comparative comprehensive study of their structure has been carried out using X-ray diffraction analysis, scanning electron microscopy, low-temperature nitrogen adsorption, and small-angle polarized neutron scattering. It has been established that the resulting iron oxide nanopowders are porous systems that, depending on the synthesis method, have a one-level, two-level (for powders obtained by aqueous synthesis), or three-level (for powders obtained by the sol–gel method) hierarchical structure organization with different scales and different types of aggregation for each of the structural levels, and the characteristic size for the larger level in both cases is >45 nm [...]
