Research Mission
The Physical Metallurgy group focuses on the development of metallic and intermetallic materials for extreme application conditions. The identification of suitable alloy compositions and tailoring of the microstructures is particular aim of our work.
The investigation and optimization of materials for engines operating at high temperatures is of central interest. Outstanding high temperature stability (mechanical and microstructural) in conjunction with reasonable toughness at room temperature as well as suitable oxidation resistance are the main objectives in this case. Furthermore, other extreme application conditions became relevant over time, for example deformation at cryogenic temperatures close to 0 K. The research activities all have the identification of fundamental mechanisms of the important phenomena, their relationship to materials properties and application to materials tailoring in common. In order to address these objectives, we routinely apply various materials synthesis techniques and scale-bridging characterization methods.
Synthesis of New Materials
The synthesis of new materials is based on the following methods that are available in house:
- cast metallurgy: arc melter and zone melting
- powder metallurgy: attritor grinding mill, planetary ball mill, hot uniaxial pressing
- heat treatments in various atmospheres
Characterization Methods
The characterization of mechanical and thermo-physical properties as well as microstructure of metallic and intermetallic materials is performed by means of:
- standard metallographic procedures
- mechanical testing under various loading conditions (tension, compression, cyclic, creep conditions, various atmospheres)
- thermal analysis: thermogravimetry (TGA) and differential scanning calorimetry (DSC)
- focused ion beam (FIB) for microscopic preparation
- analytical scanning electron microscopy: energy-dispersive X-ray spectroscopy (EDX) and electron backscatter diffraction (EBSD)
- X-ray diffraction (XRD)
- 3D atom probe tomography (APT)
During this year's MSE conference organized by Deutsche Gesellschaft für Materialkunde e.V.

In this study, our collabroative partners from IISc Bangalore and us explore the influence of off-eutectic microstructures on the mechanical properties of ternary Mo-Si-Ti alloys, with a particular focus on Ti-rich compositions in both as-cast and directionally solidified specimens. Our findings reveal the formation of nanoprecipitates of silicide and carbides due to intrinsic heat treatment during directional solidification. The nanoscale precipitates lead to strength enhancement, counterbalancing the typical reduction associated with increased microstructural length scales. In fact, the strength of the directionally solidified specimen was higher than the as cast specimen. Additionally, we observed that this increase in microstructural length scale results in improved indentation fracture toughness, offering simultaneous benefits between the trade-off mechanical properties.
This research provides valuable insights into optimizing mechanical properties in Mo-Si-Ti systems and demonstrates the significance of strategic alloy design and processing for next-generation high-temperature materials with enhanced performance.
to Scripta Materialia
Novel fine-structure austenitic-martensitic Fe-Mn-C steels are promising candidates to achieve outstanding strength and ductility combinations. By utilizing the well-known pearlite reaction, a chemical Mn pattern can be set with Mn enrichment in cementite and depletion in ferrite. This pattern remains stable even after a re-transformation back to austenite. If quenching is performed shortly after, an ultrafine lamellar microstructure with the constituting phases auf hard martensite and soft, metastable austenite gets formed.
