Postdoctoral position in High temperature corrosion of additive manufacturing materials

Department of Physics at Chalmers – home of the Graphene Flagship

Stimulated by major needs and challenges in science and a sustainable society, the ambition of the department of Physics is to foster a creative environment for academic research, learning and outreach.

We provide a competitive advantage by linking our top-level international and interdisciplinary academic performance in the areas of material science, nanotechnology and energy research with world-leading industrial R&D&I projects.

We address a wide array of experimental, computational, methodological and theoretical challenges, from fundamental physics research, through the development of new materials such as graphene to direct industrial projects generating new inventions.

We have a strong learning commitment on all levels from undergraduate to PhD studies where physics meet engineering. We are situated in a stimulating and creative environment with newly renovated facilities. The department is the major part of Gothenburg Physics Centre – a collaboration between five departments at Chalmers and Gothenburg University.


Information about the research,the project and the division
The post-doc position is located at the Division of Materials Microstructure at the Department of Physics. The division’s research is focused on understanding the relation between materials properties and their microstructure, and how this is affected by processing and how it evolves during operation. This is mainly achieved by applying advanced characterization tools, such as electron microscopy and atom probe tomography. Among the goals are to provide knowledge that can be used to develop new materials and optimize composition, production routes, heat treatment etc.

The post-doc work is part of a project on high temperature corrosion of materials and components produced by additive manufacturing (AM), which is a relatively new type of method where items are created by adding layer upon layer of a material in a computerized process, sometimes called 3D-printing. AM has great potential for components in industrial processes and firing/gasification applications, since the technique offers new possibilities to design materials and components that can withstand higher temperatures and more demanding environments. Thus, it may be possible to use AM to manufacture advanced materials/components that cannot be made by conventional methods, in order to solve critical corrosion problems in energy processes. AM produces a completely different microstructure compared to conventional manufacturing. The material’s microstructure is of crucial importance for its corrosion resistance and thereby its performance and time in service. The scientific challenge lies in understanding how the corrosion behavior of AM processed materials is affected by their characteristic microstructure. The work will involve comparisons with conventionally manufactured (e.g. cast) materials with the same (or similar) composition. The project is funded by the Swedish Energy Agency via the Swedish High Temperature Corrosion Centre (HTC), and is run in close collaboration with industry.

Major responsibilities
The main part of the work of the post-doc will be to perform controlled high temperature exposures and advanced materials analysis. The work will contain high-resolution microscoipy, by cross-section milling or thin-foil preparation using a focused ion beam, followed by microscopy, spectroscopy and diffraction, such as scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), electron backscattered diffraction (EBSD), transmission kikuchi diffraction (TKD) and occasionally scanning transmission electron microscopy (STEM). The samples may also be analysed by performing transmission electron microscopy (TEM) and associated techniques, including EDX and energy-filtered TEM (EFTEM), electron energy loss spectroscopy (EELS), high resolution TEM (HR-TEM) and scanning TEM (HR-STEM). The post-doc will be involved in developing the techniques (sample preparation, experiment set-up and data evaluation), helping PhD-students wih the techniques, and reporting the results to industry partners and university collaborators. Writing scientific papers and grant applications are also parts of the work.

Your major responsibility as postdoc is to perform your own research in a research group. The position also includes teaching on undergraduate and master’s levels as well as supervising master’s and/or PhD students to a certain extent. Another important aspect involves collaboration within academia and with society at large. The position is meritorious for future research duties within academia as well as industry/the public sector.

Position summary
Full-time temporary employment. The position is limited to a maximum of two years (1+1).

Qualifications
PhD degree (preferably in physics, chemistry or materials science). Courses taken in metallurgy, materials science, high temperature corrosion, microscopy, spectroscopy, materials characterization are considered a plus.

Skills and hands-on experience of scanning electron microscopy or high-temperatrure exposures are required. Interest and skills in building experimental research equipment and working in an inter-disciplinary area, including high temperature corrosion and advanced materials analysis are beneficial. Knowledge and hands-on experience in the following areas: specimen prepararation using focused ion beam work stations or other techniques, advanced materials analysis, such as transmission electron microscopy are of great value. Good communication and collaborative skills in English are needed. Experience from high temperature corrosion modelling and/or high temperature corrosion exposures, including designing and setting up exposure equipment is very positive.

To qualify for the position of postdoc, you must have a doctoral degree in a relevant field; the degree should generally not be older than three years. You are expected to be somewhat accustomed to teaching, and to demonstrate good potential within research and education.

The position requires sound verbal and written communication skills in English.

Chalmers continuously strives to be an attractive employer. Equality and diversity are substantial foundations in all activities at Chalmers.
