IMDEA Materials Institute is a public research organization founded in 2007 by Madrid’s regional government to carry out research of excellence in Material Science and Engineering by attracting talent from all over world to work in an international and multidisciplinary environment. IMDEA Materials has grown rapidly since its foundation and currently includes more than 120 researchers from 17 nationalities and has become one of the leading research centers in materials in Europe which has received the María de Maeztu seal of excellence from the Spanish government. The research activities have been focused in the areas of materials for transport and materials for energy and the Institute has state-of-the-art facilities for processing, characterization and simulation of advanced materials.

The influence of grain boundaries on the mechanical properties of metallic polycrystals will be analysed by means of a combination of advances experimental and simulation techniques. From the experimental viewpoint, slip transfer, grain boundary sliding and the activation of different slip systems will be analysed by means on in situ mechanical tests in the scanning electron microscope together with high-resolution digital image correlation. The experimental observations will used to validate crystal plasticity models that can account for the role of grain boundaries on the mechanical response. Overall, the thesis will lead to a deeper understanding of the effect of grain boundaries on the strength of metallic polycrystals.
Candidates should hold MSc degree in Materials Science, Metallurgy, Mechanical Engineering (or related discipline) with excellent academic credentials and a strong commitment to develop an academic career in an international and multidisciplinary environment.
Previous experience in experimental characterisation and/or numerical simulation will be valued.
Fluent English (oral and written) is required.
The candidate will be supported by a Fellowship of the Spanish Ministry of Science for 4 years to carry out his/her PhD thesis.
The thesis will be carried out in the framework of the research project "Grain Boundaries in Hexagonal microstructures: Linking processing and properties in lightweight structural alloys" (RTI2018-098245) supported by the Spanish Ministry of Science within the call Research Challenges).
The project is coordinated between IMDEA Materials Institute and the Polytechnic University of Madrid.
The position will be open until the candidate is selected.
Besides on-the-job technical training, IMDEA Materials Institute is committed to train the Institute’s scientists and staff in “soft” or transversal skills. See the available training here.
