Lehrstuhl für Werkstoffwissenschaften (Allgemeine Werkstoffeigenschaften)


Description:


The research topics of the Institute for General Materials Properties are related with the mechanical properties of structural materials in a broad sense. Testing of the mechanical properties from the nanoscale to macroscopic properties is performed on all aspects including high temperature properties, fatigue, creep, friction and wear. Our research direction is focused on understanding the properties from a micro and nanostructural basis. Therefore microsopic techniques from electron microscopy and scanning probe microscopy to optical techniques are applied to evaluate the microstructural constitution of materials on all length scales.
