hela Sverige Work Integrated Learning (WIL) is University West's overarching profile and basic principle applied to learning, the exchange of ideas, and educational development. The government has assigned the distinguished task of developing WIL to University West. Work integrated learning in education and research develops new, relevant and advanced knowledge both within the academy and among its partners, which also benefits society in general. University West offers a wide variety of study programs, has a good number of applicants and the students show a high entry rate on the labor market. The main research environments at University West are Production technology, Learning in and for the new working life and Child and youth studies and is conducted in collaboration with the surrounding society. Campus is centrally located in Trollhättan with about 13,000 students and 700 employees.
PhD Studentship in Production Technology - Specializing in Additive Manufacturing of components for Space Rockets using laser beam powder bed fusion technique
Within the Division of Subtractive and Additive Manufacturing in the research environment Production Technology West (PTW) a research group is working with additive manufacturing techniques involving powder bed fusion (PBF) methods to build 3-D geometries in metallic materials using either a laser as energy source (L-PBF) or electron beam source (EB-PBF).
This PhD project is focused on the L-PBF technique. Main areas of the research is investigating the relationships between process parameters (incl post build treatment processes such as hot isostatic pressing and heat treatment) - microstructure/defects - mechanical properties. The research group works with both process related and metallurgical related research activities. The research work in this project is conducted in close collaboration with GKN Aerospace.
The scientific work in the project
Manufacturing of metallic components with additive manufacturing techniques gains more and more interest within industry. The present PhD project is focused on high demanding space rocket applications manufactured out of a Ni-based superalloy, Alloy718. Improving the understanding of the relationship between L-PBF process parameters and their influence on the thermal/mechanical properties of the manufactured components, are key research areas of this PhD project. In addition, applying different post build processes, such as hot isostatic pressing (HIP), heat treatments or surface improvements, could have the advantage of improving material properties even further, and this will therefore also be investigated in this project. And since the project aims at space rocket applications exposed to hydrogen atmosphere, the mechanical properties of the L-PBF manufactured material in hydrogen atmosphere will also be explored and evaluated as part of this project.
The microstructures in PBF additive manufactured materials usually determines the static mechanical properties while different types of defects normally limits the dynamic mechanical properties, such as fatigue strength. In addition, limited previous work has shown that the microstructures in Alloy718 can have a significant influence on the hydrogen embrittlement effect when exposed to hydrogen atmosphere. The PhD student in this project will investigate all these areas, i.e. characterize microstructures as well as defects in L-PBF manufactured Alloy718 material and relate these to process parameters and post processing, while also investigating the relationship between microstructure and mechanical properties in air/hydrogen atmosphere.
PhD degree program: Production Technology
Research center: Doctoral students in Production Technology become members of the research group PTW (Production Technology West). The group collaborates with the engineering industry in the region at the Production Technology Centre, which houses an advanced research laboratory. For more information about our research center, go to: Production Technology Centre
Job description: The research program includes, in addition to participation in third-cycle courses and other activities, implementation of an independent thesis work. Doctoral students shall primarily devote themselves to their own education. A doctoral student may, however, be engaged to a limited extent in education, research and administration, mainly within Production Technology. Such duties, before a doctorate has been conferred, may not occupy more than 20 per cent of full-time working hours. (Higher Education Ordinance (SFS 1993:100) Chapter 5 section 2).
