The Christian Doppler Laboratory Interfaces and Precipitation (CDLIPE) treats interface-related mechanisms which affect materials processing and alloy usability. CDLIPE is funded by the Austrian Federal Ministry for Digital and Economic Affairs and the National Foundation for Research, Technology and Development. Its main goal is cutting-the-edge fundamental research which serves technological headstart of Austrian industry partners. This aim requires close collaboration between the research group Computational Materials Engineering (https://wwwt.tuwien.ac.at/forschung/werkstofftechnik/computergestuetzte_werkstoffentwicklung/) at TU Wien with the industry partners of CDLIPE. The successful candidate will thus directly obtain and contribute to deeper insight into the optimisation of technological applications and predictability of the role of process parameters for materials performance by computational materials research.
Computational prediction of the thermal evolution precipitate distributions in Al-alloy of the AA6xxx series
In previous work of CDLIPE we have characterised the influence of varying heat treatments on the precipitation response in AA6xxx alloys, in particular the distribution of intermetallic “AlFeSi” dispersoids. These particles are relevant for strength and toughness properties during alloy processing, and potential adjustments of their distribution by optimised heat treatment is promising for technological improvements. Understanding precipitation also includes questions of different nucleation sites and associated differences of nucleation energy. A deeper understanding of nucleation features, such as interface characteristics, but also the role of potential prenuclei for precipitation, allows for predictive simulations of the precipitation response due to varied heat treatments.
The aim of this thesis project is to develop a physics-based semi-empirical materials simulation routine for the varying precipitate distributions with changing thermomechanical treatments, and consequences for the materials response in terms of mechanical properties.
The candidates are expected to have a solid theoretical background in materials, preferable light metals their process technologies, and microstructures and phase stabilities and their simulative predictions, as well as strong skills in mathematics and computer use in materials science. The advertised position is associated with the faculty of mechanical and industrial engneering of TU Wien, in the research group on computational materials engineering at the institute of materials science and technology. The successful candidate will be a team member of the active research group of CDLIPE with three postdocs and four PhD students. The duration of the employment is of 3 years with possibility of extension. The extent of employment is 31 hours per week. Travelling flexibility is required, due to vital knowledge transfer between TU Wien and the project partner in the scope of frequent meetings, and presentation of results on international conferences. The annual gross salary is approximately 32,000 €. The planned start of the position is summer 2021.
Application Requirements and Procedure The candidates must have a master degree (or equivalent) in materials science or physics (or comparable fields) at the moment the PhD position starts. The application documents should contain a letter of motivation; the scientific CV with publication list, if available; higher education certificates/diplomas; the diploma/master thesis and letter(s) of recommendation. Submit applications or further inquiries to Erwin Povoden-Karadeniz. email@example.com
The deadline for applications is September 25th, 2021.
