Department of Mechanical Engineering at the Technical University of Denmark (DTU Mekanik) invites applications for a 20-month Postdoc position to work on exploring the strength limit of metals.

The Post Doc project, which is funded by the Villum Foundation through the Villum Experiment program, aims to design and synthesize a new steel with an ultrahigh strength approaching the theoretical limit. The design will be assisted by an advanced atomicscale correlative analysis combining Electron Microscopy (EM) with 3D atom probe (3DAP). The project combines plastic deformation in a top-down approach with vapor deposition in a bottom-up approach. The combination of the two approaches will allow the strengthening parameter, the grain size, to be varied from about 20 nm to 1 nm with an expected increase in strength to the theoretical limit.

Responsibilities and tasks
You will make a new steel with a grain size down to 1 nm using the vapor deposition facilities and will furthermore assist in improving the top‐down deformation approach with an aim of achieving a high strain and good formability of metals. You will also be responsible for the characterization of the microstructure and mechanical properties. We will investigate the strengthening mechanisms using advanced in-situ TEM mechanical testing down to the atomic scale together and through international collaborations.

Candidates should have a PhD degree or equivalent in the field of materials science, engineering or physics. 

The successful candidate is expected to have experience and expertise in one or more of the following subjects:     

  • Vapor deposition.
  • Thermomechanical processing.
  • In-situ TEM mechanical testing.
The Villum Experiment project is a team effort so you must be a team player besides being highly self-motivated, hard-working and independent. Excellent written and spoken English skills are mandatory.

The assessment of the applicants will be made by Senior Researcher Xiaodan Zhang and by Professor Dorte Juul Jensen.

We offer
DTU is a leading technical university globally recognized for the excellence of its research, education, innovation and scientific advice. We offer a rewarding and challenging job in an international environment. We strive for academic excellence in an environment characterized by collegial respect and academic freedom tempered by responsibility.

Salary and terms of employment
The appointment will be based on the collective agreement with the Danish Confederation of Professional Associations. The allowance will be agreed upon with the relevant union.

The workplace is the Department of Mechanical Engineering at DTU Lyngby and Risø campus. Employment should preferably start 1 March 2020, but a later start might be possible. The employment period will be 20 months.
