Integrated Computational Materials, Process and Product Engineering – IC-MPPE 2022

A carbon-containing magnesia refractory product (MgO−C) as it is applied in steel ladles of the secondary steel metallurgy was investigated for the Mode I fracture behaviour. Usually, it is determined with the wedge splitting test to quantify the thermal shock behaviour, the materials' brittleness or to gain input parameters for thermomechanical Finite Element (FE) simulations. For high...

In power semiconductor applications, thin films are of utmost importance in terms of reliability. In order to design such reliable thin films, residual stresses determination and microstructural characterization plays a crucial role. Here, various advanced techniques like FE-EBSD, FESEM-TKD (Transmission Kikuchi diffraction) and high resolution angular EBSD (HR-EBSD) are carried out to perform...

The principles of conventional residual stress analysis using XRD are explained and their further development to enable the determination of the residual stress depth profile are outlined. The actual investigations are focused on residual stress depth profiling concerning WC-Co hardmetals using X-ray diffraction techniques. Additionally, results for hardmetal samples coated with AlCrTiN layers...

An appealing idea to material scientists is to characterize the flow behavior of materials with minimal experimental effort while guaranteeing highly reliable results. Nanoindentation is one candidate technique to achieve this objective. Although established as standard method to extract hardness and Young’s modulus, the technique is not yet fully exploited regarding the determination of...
