The division of Materials and Manufacture
at Chalmers University of Technology is now looking for a highly motivated and creative PhD student who would like to contribute to the development of high entropy alloys as the new generation of advanced metallic materials for both structural and functional applications.

The research activity on high entropy alloys (HEAs) is led by Associate Professor Dr. Sheng Guo. We have a focus on the alloy design and mechanical behavior of  HEAs, or multi-principal-element alloys. We have active collaborations with both national and international colleagues in the HEAs field.

Project description
Conventional alloys including nickel-base superalloys, are typically based on one principal/major element, like Ni. The recently emerging new type of advanced metallic alloy, high entropy alloys (HEAs), however, provides a paradigm-shift in the alloy design strategy that significantly expands the scope for the exploration of new alloy systems and compositions. HEAs typically consist of at least four principal metallic elements in near-equiatomic ratios, and therefore have a higher configuration entropy than that in conventional alloys (this explains how they are termed as HEAs). Due to their unique features notably including high softening resistance at elevated temperatures and the slow diffusion kinetics, HEAs naturally possess the advantages to be considered as a new type of high-temperature materials. If these unique advantages can be further combined with the high melting temperature of refractory elements, the idea of refractory HEAs (RHEAs) would be a highly interesting alloying concept, in the context of high-temperature applications.

Nevertheless, there is still a long way to go before RHEAs can be applied as high-temperature structural materials in practice. The challenge is that, the material requirements to achieve ductile, high-strength and oxidation resistant RHEAs are rather contradictory, similar to the scenario that is facing conventional refractory alloys. In addition, how to efficiently design novel RHEAs with desirable properties is also quite a challenge. The current PhD project is aimed to tackle the challenges, by combining established and complementary expertise from Chalmers on the alloy development of HEAs, with that from KTH on computational thermodynamics.

Major responsibilities
The majority of your working time will be devoted to research within the project and the courses. You are expected to develop your own scientific concepts and communicate the results of your research verbally and in writing. You have the obligation in teaching assistance (<20%).

Position summary
Full-time temporary employment. The position is limited to a maximum of five years.

Qualifications
To qualify for this position, you should have:
- A Master degree corresponding to at least 240 higher education credits awarded by an internationally recognized university, in metallurgy, materials science, mechanical engineering, physics or relevant subjects.
- Proven research experience and good knowledge on alloy preparation, microstructural characterization and mechanical testing of metallic materials.
- Previous research experience with high-temperature materials and/or oxidation resistant materials will be considered as very beneficial.
- Excellent English skills, both verbal and written.

To be successful during your PhD, beyond demanded education and research experience, you need to be hard working, highly motivated, creative, ambitious to excel in research, able to work on your own, and also collaborate with other group members and our research collaborators.

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

Information about the department and the division
The main competencies at the department of Industrial and Materials Science are found in the areas of: Human-Technology Interaction | Form and Function | Modeling and Simulation | Product Development | Material | Production and in the interaction between these areas. The research develops the industrial process, from need to finished product while creating added value. To combine skills throughout the whole chain distinguishes the department both nationally and internationally. Here we gather internationally prominent researchers, in dynamic and outstanding research environments, as well as in national and international research networks.

The division of Materials and Manufacture covers the entire value chain from materials design, processing and characterisation to machining of primarily metals. We employ a range of technologies – casting, powder metallurgy, electroplating, additive manufacturing and material removal – and a range of advanced characterisation techniques. Our work is interdisciplinary by nature and is addressing topics that have a direct impact on sustainability. The division is collaborating closely with other universities and research institutes and is implementing industry-academia partnerships through collaborative projects and strategic initiatives such as the Chalmers Centre for Metal Cutting Research (MCR), and Centre for Additive Manufacture - Metal (CAM2).



Chalmers University of Technology conducts research and education in engineering sciences, architecture, technology-related mathematical sciences, natural and nautical sciences, working in close collaboration with industry and society. The strategy for scientific excellence focuses on our eight Areas of Advance; Building Futures, Energy, Information & Communication Technology, Life Science, Materials Science, Nanoscience & Nanotechnology, Production and Transport. The aim is to make an active contribution to a sustainable future using the basic sciences as a foundation and innovation and entrepreneurship as the central driving forces. Chalmers has around 11,000 students and 3,000 employees. New knowledge and improved technology have characterised Chalmers since its foundation in 1829, completely in accordance with the will of William Chalmers and his motto: Avancez!
