  • Process simulation of Direct Energy Deposition

    at the Division of Mechanics of Functional Materials in the institute of Material Science, TU Darmstadt

    2025/04/10

    Direct Energy Deposition (DED) is an additive manufacturing technique that uses a focused energy source to melt and deposit material layer by layer, enabling the production of complex components. It has numerous industrial applications due to the high precision it offers and the flexibility in material selection. Materials include severa high strength alloys such as titanium alloys, stainless steel and nicked bases alloys.

    Process simulation plays a crucial role in predicting and controlling the additive manufacturing (AM) process, enabling the optimization of efficiency, quality, and reliability of the produced parts. The candidate will focus on simulating the DED process using the Fe20Cr material system. Thermo-structural evolution and effects of process parameters are to be studied.

  • Micromagnetic modelling of grain boundary regions in iron-silicon systems

    at the Division of Mechanics of Functional Materials in the institute of Material Science, TU Darmstadt

    Iron-Silicon alloys play an important role in electricity generation as well as transmission and electric mobility. During frequent magnetic cycling energy is lost through various processes, reducing these losses poses a major challenge to the design of next generation electrical machines. In this manner investigating the relationship between microstructure, local features, energy losses and hysteresis behavior is investigated.

    This work belongs to part of the collaborative research center (CRC) and Transregio (TRR) 361 with an international consortium of universities, funded by DFG and FWF. The candidate will work on simulation of the influences of local features in proximity of grain boundaries on the hysteresis behavior. The results of these simulations will furthermore be used to set up a neural network informed by these results.

  • Polymer-derived ceramics (PDCs) can be obtained upon pyrolysis of suitable inorganic polymers in inert or reactive atmosphere.[1-3] An important characteristic of PDCs is the strong relationship between the molecular structure and chemistry of the polymers, their processing and the nanostructure and properties of the resulting ceramics.[2] They are nanoscopically heterogeneous and composed of nanodomains. This feature is controlled by the nature and organization of the segregated carbon formed during the polymer-to-ceramic conversion.[2,4,5] Due to their specific features such as tunable electrical, dielectrical, optical and thermal properties, PDCs can act as multifunctional materials performing multiple functions in a system.[1-5]

  • In response to the changing global landscape, energy has become a primary focus of the major world powers and scientific community. There has been great interest in developing and refining more efficient energy storage devices. One such device, the supercapacitor, has matured significantly over the last decade and emerged with the potential to facilitate major advances in energy storage. Supercapacitors, also known as ultracapacitors or electrochemical capacitors, utilize high surface area electrode materials and thin electrolytic dielectrics to achieve capacitances several orders of magnitude larger than conventional capacitors [1]. In doing so, supercapacitors are able to attain greater energy densities while still maintaining the characteristic high power density of conventional capacitors.
