Grain Boundary Relaxation in 18-carat Yellow Gold

Daniele Mari, Robert Schaller, Iva Tkalcec Vâju

Au60Ag30Cu10 (in at%) gold alloy exhibits a mechanical loss spectrum composed of a Zener peak due to Cu atoms in the solid solution and of a second relaxation peak at higher temperature or lower frequency. It is shown that this second peak is related to th ...

Smart Building Designer: Eine Methode zur optimalen Auslegung von komplexen Gebäudesystemen

Araz Ashouri

As decided by the European Parliament in April 2009, starting from 2019, new buildings must be so-called net-zero energy buildings. The capital cost of these building systems and thus the potential for optimization will increase significantly. In addition, ...
