At the Department of Materials Science and Engineering we are offering a postdoctoral researcher position for development and implementation of crystal plasticity finite element method (CPFEM) modelling of complex microstructures in metallic materials under various loading condition. In order to design novel alloys and microstructures for load-bearing applications it is necessary to understand the evolution of local micro/macro-stresses and strains within the microstructures and at phase/grain boundaries is critical. Therefore, we the main aim of the position is to develop and implement microstructure-sensitive multi-scale computational models for prediction of mechanical behavior of complex multiphase microstructures under static and cyclic loading conditions. This work will support ongoing experimental activities on understanding the structure-property relationships of metallic materials. The CPFEM modelling will in particular support experimental studies using single grain mapping (3DXRD) of mechanical behavior of polycrystalline aggregates as well as experimental studies of structure-property correlations under fatigue loading.

The position should be highly interesting for researchers in computational materials science with a desire to deepen their knowledge and expand capabilities in the field of mechanical metallurgy and materials modeling. Furthermore, the postdoc will have excellent opportunity to widen their knowledge in physical metallurgy in general and to collaborate intensively with academic and industrial partners in Sweden and internationally as well as to contribute to large-scale infrastructure (synchrotron facility) research.

At the Department of Materials Science, we offer a postdoctoral position in synchrotron light and neutron characterization of metallic engineering materials to increase the understanding of these materials and their processes. In this way, we want to enable green transitions in industry where new materials and process solutions can be designed with the help of the fundamental understanding that is generated. Large-scale infrastructures generating synchrotron light and neutrons enable very efficient studies of material processes in real time during manufacture and use. And real-time studies mean that the understanding of mechanisms that control the behavior of materials can be improved and then used for new material innovations. For example. we work on improving metallic materials used in the electrification of the automotive industry, hydrogen-tolerant metallic materials that are required for the transition to a fossil-free energy system with hydrogen as an important energy carrier, and the design of metallic materials that are better suited for production from recycled materials while maintaining high performance.

So-called in-situ/in-operando and high-throughput measurements are particularly important in this project and the postdoc will both work on developing measurement methodology and data analysis for these types of experiments and also work with the applications, i.e. better understanding of the microstructure and mechanical properties of specific metallic materials. More specifically, the postdoc will work with phase transformations in metallic materials and deformation of metallic materials.

The postdoc position should be very interesting for researchers in materials science with a characterization profile and the desire to deepen their knowledge and expand their capacity in the field of physical metallurgy and material characterization. Furthermore, the postdoctoral fellow will have an excellent opportunity to collaborate closely with academic and industrial partners in Sweden and internationally, as well as to contribute to research at large-scale infrastructures (synchrotron light facilities).

In many countries, used nuclear fuel will be placed in geological repositories to protect the biosphere from radioactivity. Within the EU-project EURAD-2, several aspects of storing radioactive waste in geological repositories will be studied. The part of the project that will be carried out at KTH consists of two parts. KTH will carry out experimental studies of radiation induced dissolution of UO2-based model materials and also develop and evaluate mechanistic descriptions of processes contributing to the dissolution. The descriptions will be included in numerical models for simulation of radiation induced dissolution of used nuclear fuel.  The latter part of the project will be carried out in close collaboration with computer programmers.

Materials in nuclear technological installations are exposed to high doses of ionizing radiation. For the design of sustainable solutions, knowledge about how radiation affect materials is necessary. The work in this project is focused on experimental studies of radiation induced chemical processes in systems for reprocessing of used nuclear fuel. This includes studies of the radiation chemistry of liquids and liquid-mixtures of relevance in reprocessing and studies of radiation induced corrosion of solid materials in contact with these liquids.
