The Helmholtz-Zentrum Geesthacht (HZG), in Geesthacht, near Hamburg, and in Teltow, near Berlin, conducts materials and coastal research. For further information please refer to: www.hzg.de
HZG is one of the 19 national institutions of the Hermann von Helmholtz Association of German Research Centres e.V. (HGF). Around 1,000 employees carry out basic research and development work in close cooperation with national and international research institutions, research-oriented clinics and economic and public institutions.
At the Institute of Materials Research some 200 scientists conduct research in the five sub-institutes "Materials Mechanics", "Materials Physics", "Materials Technology", "Magnesium Innovation Centre MagIC" and "Metallic Biomaterials".
PhD Position (m/f/d) Characterisation of the degradation of magnesium under load
Reference code: 50033326_2 – 2020/WB 4 Commencement date: as soon as possible The place of employment is Hamburg.
The Institute of Materials Research, Division Metallic Biomaterials at HZG focusses on the development of Magnesium (Mg)-based alloys for specific applications such as biodegradable implants. Especially for biomedical Mg-based devices, it is crucial to understand and model the mechanisms governing the interactions between alloy composition and microstructure on one side and mechanical as well as corrosive properties on the other side. The challenge is the complex biological environment under which the implant has to operate and eventually dissolve. One important piece of additional information is the influence of load on the degradation behaviour under physiological conditions that shall be addressed within the framework of this project.
Within this framework, we are offering a PhD position (m/f/d) for the characterisation of the degradation of magnesium under load. The position is initially limited to three years.
Your responsibility within this project will be the investigation of Mg alloys under load in corrosive environments, to generate a comprehensive data space. This provides the experimental background to develop a digital twin of the material and the corrosion process by the modelling side of the project. In order to achieve this you will need to plan and conduct experiments (ex situ and in situ) aiming at the characterisation of the influence of mechanical load on the degradation of the material and to evaluate the results. This includes the use of standard laboratory techniques (e.g. X-ray diffraction, optical and scanning electron microscopy) as well as advanced synchrotron-radiation-based methods e.g. micro computed tomography and grain mapping. After the evaluation and analysis, you will need to hand over the results to the modellers in a structured form, which enables their further processing.
master’s degree or diploma in Physics, Material Science, Engineering or a related discipline
strong analytical and experimental skills
background knowledge in computer programming (e.g. MatLab, C++) is necessary
background knowledge in the field of materials research and corresponding analytical techniques is required
experience with X-ray diffraction or X-ray imaging is strongly desired
team spirit, pro-active attitude, good communication skills and the ability to work efficiently in an interdisciplinary team has to be proven
proof of good written and spoken command of English is required (e.g. TOEFL, IELTS)
We offer you
multinational work environment with over 1,000 colleagues from more than 50 nations
extensive options of vocational training (i. a. expert seminars, language courses or leadership seminars)
flexible working hours and various models to ensure the compatibility of family and career
excellent infrastructure, including a scientific in-house library as well as modern work spaces
an appropriate salary related to the German public tariff (TV-AVH) plus the usual social benefits for the public employment sector
The promotion of equal rights is a matter of course for us. Severely disabled persons and those equaling severely disabled persons who are equally suitable for the position will be considered preferentially within the framework of legal requirements.
Interested? Then we are looking forward to receiving your comprehensive application documents (cover letter, CV, transcripts, certificates etc.) indicating the reference number 2020/WB 4.

About Helmholtz-Zentrum Geesthacht (HZG)
The Helmholtz-Zentrum Geesthacht, Centre for Materials and Coastal Research (HZG) and is one out of 19 autonomous research centers of the Helmholtz Associciation. The HZG is a non-profit making research institute with limited liability.
As a member of the Helmholtz Association of German Research Centres, the largest scientific organization in the country, the Helmholtz-Zentrum Geesthacht is engaged in long-term activities in the fields of materials and coastal research that are making a major contribution to resolving the large and pressing issues facing society and the scientific and business worlds.
The main site of the Helmholtz-Zentrum Geesthacht lies in the south of Schleswig-Holstein in Geesthacht, directly at the River Elbe. More than 50 small and large buildings are scattered over about six square kilometres to house the numerous laboratories, workshops and offices. In Geesthacht, at the site in Teltow near Potsdam, and at outposts in Hamburg and Munich, the Centre provides around 1000 employees from around 50 nations a modern and international working environment.
The Research Centre was founded back in 1956 and today is the largest non-university research facilit...y in Schleswig-Holstein. It has a budget of more than 90 million Euros a year, around 65 million of this financed by the German federal government and the four federal states. The state of Schleswig-Holstein pays around 5% of this, the Free and Hanseatic City of Hamburg around 2%, and the states of Lower Saxony and Brandenburg each pay 1%. The majority, amounting to 90%, comes from federal funds awarded via the Helmholtz Association in an evaluated procedure.
