Offer Description
PhD studentship in production technology specialising in welding based additive manufacturing of superalloys
Research in the division of mechanical engineering in the department of engineering science focuses on three main areas in relation to welding technology; metallurgy, process physics modelling, and process development & control. Our main aim is to fundamentally study and improve understanding of welding processes and their influence on materials. In a new project in cooperation with a consortium of ten different industrial companies, we are seeking a PhD student for a position at University West.
The scientific part of the project
Additive manufacturing (AM) techniques involving both directed energy deposition (DED) and powder-bed fusion (PBF) are attracting increasing attention for fabrication of complex structures not possible via traditional machining, and with minimal material wastage. Considerable research effort has been devoted worldwide towards investigation of the above AM routes for building of metallic parts using materials ranging from steels to superalloys. At University West, too, a strong research environment in AM spanning both DED and PBF of the above materials has taken shape with the aid of numerous funded projects implemented in close co-operation with industry. However, there has been very limited previous work globally addressing superalloys and DED.
The PhD project will focus on the development of superalloy structures, and specifically shedding light on how to prevent cracking of these class of alloys during DED as well as post processing. This will demand systematic experimental studies that will investigate build characteristics such as microstructures, phase constitution etc., besides functional properties such as static as well as dynamic loading of the built structures.
Potential research questions include:
- What is the parametric impact of DED process variables on geometry, microstructure and phase constitution of superalloy builds?
- What are the governing and fundamental reasons for cracking during the DED process?
- How are material property characteristics such as static and cyclic superalloy builds influenced by process parameters?
Doctoral degree program:Production Technology
Research center:
Doctoral students in Production Technology become members of the research group KAM-PT (complete academic environment in production technology). The group collaborates with the engineering industry in the region at the Production Technology Centre, which houses an advanced research laboratory. Click here for more information about our research center.
Job description:
The research program includes, in addition to participation in third-cycle courses and other activities, the implementation of 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 percent of full-time working hours. (Higher Education Ordinance (SFS 1993:100) Chapter 5 section 2 ).
Qualification requirements:
To qualify for appointment as a PhD, two eligibility requirements must be met: 1) basic eligibility and 2) special eligibility
1) The basic eligibility requirements for doctoral programs as set out in the higher education ordinance are as follows:
- a degree at master’s level,
- completed courses totaling at least 240 university credits of which a minimum of 60 at master’s level or,
- substantially equivalent knowledge gained in some other way whether in Sweden or abroad.
2) To fulfil the special eligibility requirements for a doctoral degree in production technology, a student must hold a degree at master’s level in a subject relevant to the doctoral degree subject. With a thesis project corresponding to at least half a year of study. The eligibility requirements may be fulfilled by studies in Sweden or abroad.
For more information please read 3.1 and 3.2 in General syllabus for the third-cycle programme in Production Technology, Ref. No U 2021/160.
Additional Qualifications:
Mandatory:
- A degree at master’s level in material science or equivalent
- Documented knowledge of materials processing (welding, cladding, additive manufacturing) or layer-by-layer deposition (such as wire-arc AM, thermal spray etc.)
- Documented knowledge of microstructure of superalloys or steel
- Documented experience in microstructural characterization using techniques such as optical microscopy, SEM etc.
- Documented ability in oral and written English communication
Other relevant but not mandatory qualifications:
- Knowledge of laser directed energy deposition and wire arc additive manufacturing
- Experience in advanced characterization using techniques such as XRD, TEM etc.
- Experience in material testing such as tensile and fatigue
- Experience in materials modelling and thermodynamics
- Knowledge of superalloys
- Demonstrated research experience and scientific writing skill in the form of prior publication
- Willingness to travel and perform experiments outside of University West if needed
- Ability to communicate in Swedish
Selection:
The basic factor for selection among qualified applicants is the ability to profit from such a program. For more information, please read 3.3 in General syllabus for the third-cycle programme in Production Technology, Ref. No U 2021/160.
We believe that a successful applicant should have a genuine interest in the development of mathematical models of physics. It will also be essential to actively take part in the experimental verification of the developed software and algorithms (optimization schemes). For this reason, the ability to work well in a group with other employees and students is necessary.
Duration and terms of employment:
Employment as a doctoral student shall be on an open-ended basis but not for longer than to a specific point in time and never for a period extending more than one year after receiving the doctoral degree. The initial appointment must not be for more than one year. The appointment may be renewed for no more than two years at a time. A person may be employed as a research student for a total of not more than eight years. The total period of employment, however, may not exceed the equivalent of four years of full-time study at the third level of higher education. (Higher Education Ordinance (SFS 1993:100) Chapter 5 section 7 ). If 20% of the working hours are dedicated to education and administration, this normally means an employment of 5 years.
Application
Applications are to be submitted electronically through the University West web-based recruitment tool, Varbi.
The application must include:
- CV/Personal qualifications
- Personal letter containing:
- Interest in the research topic
- Previous experience regarding the proposed research topic and its research methods and scientific theories
- Motive to pursue doctoral studies
- Degree project of second level of higher education
- Degree certificate of first and second level of higher educationin the original language and in translation
- Diploma Supplement in original language and in translation
- Course list/transcript of all semesters for bachelor's and master's degrees in original language and in translation
- Other documents which the applicant wishes to invoke
If your degree is from a university outside of Sweden, make sure that you attach a diploma and full transcripts that makes assessing your degree easier. If your degree has not been verified by a Swedish authority you need to provide contact details to the issuing university, registrar or similar, that can verify the degree at our request.
Approved written languages regarding papers, diplomas, grades and other relevant documents are the Scandinavian languages and English, or translations into those languages. Attach the original when submitting translated documents.
Documents that cannot be sent digitally, should be marked with ref.no R 2024/39 sent to:
