Modelling the influence of strain fields around precipitates on defect equilibria and kinetics under irradiation in ODS steels: A multi scale approach
Resistance to radiation damage is a crucial property for structural materials in fission or fusion reactors. The particle-matrix interface in oxide dispersion strengthened (ODS) steels is considered a sink for point defects created during irradiation. In this work we address the question, if elastic strain fields around oxide particles cause a long-range interaction between the precipitates and point defects. We use kinetic Monte Carlo simulations to simulate the diffusion of point defects under the influence of elastic strain fields caused by Y2O3 and Y2Ti2O7 precipitates.
Post-doc position in microstructure modeling at Nanyang Technological University (NTU) Singapore
The Additive Microstructure Engineering Laboratory (AddME Lab) in the school of Mechanical and Aerospace Engineering at NTU (Singapore) is a young, diverse, and interdisciplinary research group with interests in in-line microstructure control and assessment during selective laser melting (SLM) processes. In this framework, we are collaborating with the Institute of High Performance Computing under the Agency for Science, Technology and Research (A*STAR), to simulate the microstructure of metals produced during SLM.

Improved oxidation resistance of high emissivity coatings for reusable space systems
Here novel disilicides were explored for use in heat shields.
WSi2 and MoSi2 were applied as coatings on an insulating zirconia substrate.
The high emissivity of these compounds and their mixtures, makes them very attractive for use in spacecraft.
Compressive performance of MAX phase composites
Compressive performance and crack propagation in MAX phase composites
Here micro CT was used to reveal the structure performance relationships in metal/ceramic composites based on Ti2AlC / Al alloy combinations.
The results show the promise of infiltrated max phase materials in the production of high performance composites.
