About the job

The Department of Mechanical and Industrial Engineering (MTP) has a vacancy for a PhD candidate in the materials research group, with special focus on the design and development of hydrogen resistant metallic materials by additive manufacturing.

Hydrogen is considered as a clean energy carrier for the transition from fossil fuels to renewable energy. However, the application of hydrogen energy can be decelerated due to the inevitable embrittling effect when hydrogen interacts with metal. Additive manufacturing (AM) has shown its uniqueness in producing complex multifunctional components for existing applications. It has also been proposed as a promising approach to develop metallic materials that can tolerant hydrogen damage, not only in the hydrogen value chain, but also for subsea service in the oil and gas sector. Nevertheless, little is known about hydrogen embrittlement resistance of AM materials. In this project, you are expected to employ the state-of-the-art testing techniques developed at MTP, to study both the AM and conventional metallic materials, for instance high-strength steels and nickel alloys, on:

  • Hydrogen uptake, diffusion and trapping. Because testing in hydrogen gas is expensive and requires dedicated experimental setup, an equivalence between gaseous and electrochemical hydrogen will be established
  • the effect of hydrogen on macro- and micro-mechanical properties
  • the effect of AM parameters on hydrogen embrittlement resistance

For a position as a PhD Candidate, the goal is a completed doctoral education up to an obtained doctoral degree.

Your immediate leader is Associate Professor.

Duties of the position

  • study hydrogen uptake, diffusion and trapping behavior of materials using hydrogen permeation and thermal desorption spectroscopy techniques
  • establish an equivalence between gaseous and electrochemical hydrogen charging
  • study and compare hydrogen effect on mechanical properties of AM and conventional materials using tensile testing and micro-mechanical testing approaches
  • materials characterization using SEM, XRD, FIB, etc.
  • write journal papers
  • present scientific work at conferences

Required selection criteria

  • you must have a professionally relevant background in materials science/engineering, metallurgical engineering, mechanical engineering, experimental physics, or related fields
  • you must have experimental skills in mechanical testing and microstructural characterization of materials
  • you must have a scientific background relevant to the planned research activities
  • your education must correspond to a five-year Norwegian degree program, where 120 credits are obtained at master's level
  • you must have a strong academic background from your previous studies and an average grade from the master's degree program, or equivalent education, which is equal to B or better compared with NTNU's grading scale. If you do not have letter grades from previous studies, you must have an equally good academic basis. If you have a weaker grade background, you may be assessed if you can document that you are particularly suitable for a PhD education.
  • you must meet the requirements for admission to the faculty's doctoral program
  • you must show the ability and willingness to conduct research in a multidisciplinary setting and team
  • good written and oral English language skills

The appointment is to be made in accordance with  Regulations concerning the degrees of Philosophiae Doctor (PhD) and Philosodophiae Doctor (PhD) in artistic research national guidelines for appointment as PhD, post doctor and research assistant  

Preferred selection criteria

  • prior knowledge/experience in hydrogen embrittlement phenomenon of structural materials
  • prior knowledge on additive manufacturing or power metallurgy
  • knowledge of programming basics like Python, Matlab, etc.
  • experience with research projects, or industrial experience

Personal characteristics

  • motivated, enthusiastic and result oriented
  • independent, self-going and progress-oriented
  • motivated to embrace challenges
  • good communication skills
  • good collaborative capabilities

Emphasis will be placed on personal and interpersonal qualities.

Salary and conditions

As a PhD candidate (code 1017) you are normally paid from gross NOK 501 200 per annum before tax, depending on qualifications and seniority. From the salary, 2% is deducted as a contribution to the Norwegian Public Service Pension Fund.

The period of employment is 3 years.

Appointment to a PhD position requires that you are admitted to the PhD programme in Engineering  within three months of employment, and that you participate in an organized PhD programme during the employment period.

The engagement is to be made in accordance with the regulations in force concerning State Employees and Civil Servants, and the acts relating to Control of the Export of Strategic Goods, Services and Technology. Candidates who by assessment of the application and attachment are seen to conflict with the criteria in the latter law will be prohibited from recruitment to NTNU. After the appointment you must assume that there may be changes in the area of work.

It is a prerequisite you can be present at and accessible to the institution daily.

About the application

The application and supporting documentation to be used as the basis for the assessment must be in English.

Publications and other scientific work must follow the application. Please note that your application will be considered based solely on information submitted by the application deadline. You must therefore ensure that your application clearly demonstrates how your skills and experience fulfil the criteria specified above.

The application must include: 

  • CV and certificates
  • transcripts and diplomas for bachelor's and master's degrees. If you have not completed the master's degree, you must submit a confirmation that the master's thesis has been submitted
  • a copy of the master's thesis. If you recently have submitted your master's thesis, you can attach a draft of the thesis. Documentation of a completed master's degree must be presented before taking up the position
  • cover letter justifying your interest and fit for the position
  • research plan or project proposal (maximum 2 pages, Times New Roman or similar Font 11, Single spacing)
  • name and contact information of three referees
  • academic works - published or unpublished - that you would like to be considered in the assessment (up to 10 works)

If all, or parts, of your education has been taken abroad, we also ask you to attach documentation of the scope and quality of your entire education, both bachelor's and master's education, in addition to other higher education. Description of the documentation required can be found here. If you already have a statement from NOKUT, please attach this as well.

We will take joint work into account. If it is difficult to identify your efforts in the joint work, you must enclose a short description of your participation.

The position requires spoken and written fluency in the English language. Applicants from non-English-speaking countries outside Europe must document English skills by an approved test. Approved tests are TOEFL, IELTS and Cambridge Certificate in Advanced English (CAE) or Cambridge Certificate of Proficiency in English (CPE).
