Institute for Applied Materials – Materials Science and Engineering

PhD positions within the RTG 2561 MatCom-ComMat

The Research Training Group (RTG 2561) MatCom-ComMat: Materials Compounds from Composite Materials for Applications in Extreme Conditions funded by the Deutsche Forschungsgemeinschaft (DFG) offers several PhD positions at Karlsruhe Institute of Technology (KIT), Technical University Darmstadt and Dechema Research Institute in Frankfurt, starting in April 2020.

The scope of the RTG relates to the development, characterization and modelling of novel, revolutionary multi-phase composite systems capable of withstanding temperatures substantially beyond 1300 °C and harsh environmental conditions (e.g., oxidative, corrosive, erosive atmospheres) as far as mechanical behaviour, environmental resistance and durability are concerned. This is achieved by a materials combination consisting of metallic/intermetallic alloys based on refractory metal silicide alloys as sub-strates and polymer-derived ceramic nanocomposites based on Si(Metal)CON.

Within this RTG, PhD researchers will be trained in a structured, coordinated and multidisciplinary manner to address the following aspects: (A) Synthesis of the composite materials in lab scale with tailor-made microstructures and properties; (B) Analysing the feasibility of large-scale manufacturing processes for the materials compounds; (C) Understanding the fundamental relations between synthesis, microstructure and properties of novel complex composite materials, this includes the determination of properties with state-of-the-art methods and techniques; (D) Making reliable scale-bridging simulations and predictions based on the materials microstructures and properties for typical engineering applications.

Up to twelve doctoral researchers will be supervised by teams of highly qualified scientists/professors amongst the three institutions and will be able to take advantage of their complementary expertise by visiting the partner institutions for extended periods. Likewise, stays abroad at internationally known academic institutions are encouraged.

Successful candidates should have completed their master studies in the fields of mechanical or chemical engineering, materials science or physics/chemistry as well as in related fields. The three institutions are equal opportunity employers. Women are especially encouraged to apply. Applicants with disabilities will be preferentially considered if equally qualified. Please send your complete professional CV, including your educational background and experience as well as a brief statement of your research in-terests until March, 1st, 2020 to the speaker of the RTG, Prof. Dr.-Ing. Martin Heilmaier.
