  • PhD position: Impact of Fermi Energy on Microstructure Evolution: An electro-chemo-mechanical phase-field study (DFG)

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

    2023/05/01

    Dopants can largely affect the properties of functional perovskite ceramics through their influence on the lattice-based intrinsic properties and their impact on the property- determined microstructure characteristics. For successful Fermi-level engineering of oxide ceramics, one crucial step is thus to understand the correlation among doping, processing, and the resultant microstructure characteristics. One of the major challenges lies in the multiphysics involvement.

    This project aims to develop an electro-chemo-mechanical and Fermi-level informed phase- field grain growth model to study the microstructure evolution of perovskite oxides. The developed theory will be demonstrated for doped BaTiO3 as the prototype perovskite system. Results will reveal the formation mechanisms of GB segregation, microstructure evolution, and the resultant microstructure characteristics and their dependency on the dopants and the Fermi Energy Levels (FELs).

  • 2 Student Research Assistant Positions (Hiwis, 40h per month each)

    at the Collaborative Research Centre (CRC) 1548 – FLAIR Group

    2023/05/11

    Assistant scientists

    Within the CRC FLAIR we established an integrated Research Training Group (MGK) which aims at the education and training of a new multidisciplinary generation of functional oxide researchers in Germany and qualifying the doctoral researchers for their future careers in academia and industry. The overall features of the proposed MGK include interdisciplinary coaching of young material scientists, development of professional career skills, and integration in modern project and data management. Measures to ensure these features are implemented within a diverse multi-level qualification program concerning both scientific and professional skills and a well-thought supervision concept for doctoral researchers and post-doctoral support. For continuous improvement, constant evaluation of the MGK will be carried out based on the feedback of doctoral candidates, PIs and associates. You will find detailed information about our research projects on our Junior FLAIR – FLAIR – TU Darmstadt (tu-darmstadt.de) website.

    We are looking for two motivated students to provide technical and office supports to implement our MGK measures.

  • Powder Bed Fusion Simulation of Aluminum Engineering Alloys

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

    2023/05/11

    Bachelor Thesis, Advanced Research Lab, Master Thesis

    Powder bed fusion (PBF) is a promising technique for improving the engineering alloys, such as 316L stainless steel, aluminum alloys (AlSi10Mg, AlSi12Mg, etc), and Ti6Al4V titanium alloy. The addition of ceramic nanoparticles will further enhance the mechanical strength (notably the compression strength) of these alloys. Multiscale PBF simulation forms the first step to enable the data-driven optimization of the nanoparticle-additivation for such PBF-produced engineering alloys.

    This work belongs to part of inter-laboratory study (ILS) with a consortium of universities participating a DFG-funded priority program. The candidate will work on simulation the influence of processing parameters on the properties of PBF processed AlSi10Mg. The impact of the processing parameters on the structural and mechanical properties will also be investigated by thermo-elasto-plastic simulations.

    Rechargeable Li-ion batteries have been widely applied not only in electronic devices but also as one of the major sources for the storage of renewable energies. Li-ion batteries work by the transfer of lithium ions between the cathode and anode electrodes during charge-discharge cycles. During these cycles, the battery electrodes experience mechanical stresses and strains that cause deformation. Cathode materials like LiMn2O4 experience small strains that can be analysed using linear strain theory. To analyze these deformations, the chemo-mechanics coupled formulation needs to develop.

    In this work, we will develop the chemo-mechanics formulation for thin structures like beams. For this IGA solid beam element will be considered and coupled with the ion diffusion equation. After the implementation in MATLAB code, the performance of the formulation will be evaluated on several benchmark problems.

  • Powder Bed Fusion Simulation of Nd-Fe-B Permanent Magnet

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

    2023/03/03

    Bachelor Thesis, Advanced Research Lab, Master Thesis

    Powder bed fusion (PBF) is a promising technique for improving the magnetic performance of NdFeB permanent magnets. However, one major challenge encountered in PBF processed NdFeB parts is high thermal stresses associated with low thermal conductivity and innate brittleness of NdFeB. These stresses can induce micro-cracks and lack-of-fusion pores consequently affecting the magnetic performance of processed products. A way to reduce these stresses is to increase the porosity in the microstructure by adjusting the processing parameters like laser power and scan speed. This work focuses on the influence of processing parameters on the porosity of PBF processed NdFeB. The impact of the processing parameters on the magnetic properties will also be investigated by magnetostatic simulations
