ICAMS focuses on the development and application of a new generation of simulation tools for multi-scale materials modelling with the aim of reducing development cost and time for new materials. The different length scales from the atomic structure to macroscopic properties of materials are bridged by an interdisciplinary team of scientists from engineering, materials science, chemistry, physics and mathematics.

The urgent need to decarbonise our society leads to core challenges in the transition from fossil to H-based fuels that affect also gas turbines for power generation. It is becoming increasingly critical that hydrogen (H) is integrated into materials design principles and in lifetime predictions of engineering parts. The goal of this project on Ni-based superalloy is to reveal the influence of H on the microstructure, the interaction of H with different alloying elements and the influence of H on creep. The PhD student will perform large-scale atomistic simulations with accurate accounting for H-metal interactions. This includes density-functional theory calculations and the development of machine-learning interatomic potentials based on the atomic-cluster expansions. The PhD project is embedded in a collaboration with experimental partners at the Ruhr-University Bochum (creep experiments of H-charged samples) and the Max-Planck-Institute for Sustainable Materials, Dusseldorf (H-sensitive scale-bridging characterization) and the industry partner ThermoCalc, Sweden (thermodynamic modelling).

Your tasks:

• High-throughput density-functional theory calculations for H in Ni-base superalloys
• Development of machine-learning interatomic potentials for H in Ni-base superalloys on the basis of the atomic cluster expansion
• Large-scale atomistic simulations of the influence of H on phase stability and mechanical properties
• Close collaboration with experimental partners (Ruhr-University Bochum and Max-Planck-Institute for Sustainable Materials, Dusseldorf) and with industrial partner (ThermoCalc, Sweden)
