  • We interviewed one of the ICARUS lead researchers, Prof. Locci and he gave us a deeper insight into the project's innovations

    To learn more about ICARUS achievements, we sat down with one of the researchers heavily involved in the project – Associate Professor in the University of Cagliari- Antonio Locci and discussed with him the results obtained in WP3.

    What were the results achieved in WP3?

    The end goal of WP3 was to develop an innovative theoretical methodology to describe the thermodynamics of multiphase multicomponent polycrystalline metal alloys and identify new thermodynamically stable nanocrystalline alloys. Classical and statistical thermodynamics were combined in a general theoretical scheme that allows describing the Gibbs free energy of different possible microstructure and systems. The resulting model can also predict the existence of thermodynamically stable nanocrystalline alloys and provides a tool for identifying them based on the available physical and chemical information.

    What can you tell us about your findings? How important were your learnings for the overall progress of the project?

    Surprising! This is the first word that comes to mind. Our findings are surprising because they represent a clear example of how science works. Immediately after the explosion of nanoscience and nanotechnology as hot topics in materials science around 1990s, thermodynamic stability was definitely ruled out for nanocrystalline alloys. Starting from the end of 1990s, a few researchers argued the possible existence of thermodynamically stable nanocrystalline alloys under very specific and hard-to-meet general conditions. A first proof of concept was given eventually a few years ago for the W-Ti system. Now, not only we show that other thermodynamically stable nanocrystalline alloys exist and they can be actually fabricated, but we also provide a tool allowing the systematic exploration of the thermodynamics of multiphase multicomponent metal alloys.

    Since its original design, ICARUS set itself very ambitious objectives. The project proposal has interpreted perfectly the FET OPEN call guidelines, proposing highly innovative and risky research activities aiming at creating a new paradigm in materials science. We have learned progressively new physics and chemistry, running after the revolutionary idea that grain boundary segregation can be the key to thermodynamic stability in nanocrystalline alloys. And we succeeded, in the end. Thus, once again, addressing difficult questions, and not restricting to those for which we have reassuring responses, is the best way to foster progress in science.

    What were the innovative techniques been used?

    We have developed a new approach to the thermodynamics of polycrystalline metal alloys starting from the classical regular solution model. In particular, we related the Gibbs free energy of the alloy to the local configuration and energy of chemical bonds in grain boundaries. The model obtained, although within specific constraints and limitations, can be tailored to the different case studies and systems.

  • ICARUS at ICMAE 2019

    The ICARUS coordinator, Nicolas A. Cordero (UBU-ICCRAM), was present at 10th International Conference on Mechanical and Aerospace Engineering (ICMAE) 2019 taking place from 22 to 25 July, 2019 in  Belgium’s capital city, Brussels. ICMAE is a global event focused on Aerospace Engineering and Mechanical. Prof. Cordero made a very interesting presentation in the afternoon of the 24th of July under the title "Modelling, fabrication & characterization of nc metal alloys for the aerospace sector: The ICARUS Project".

  • Join the ICARUS supported workshop on "Computational Methods for 2D materials"

    The ICARUS Consortium is delighted to invite you to participate in the workshop “Computational Methods for 2D materials” that will be held at the premises of University of Burgos in Burgos, Spain from Monday 17th to Thursday 20th of June, 2019.

    Are you an undergraduate or graduate student in Chemistry, Physics, Biology or Material Science related areas? The workshop on “Computational Methods for 2D materials” is addressed to you.

    Through this event students and researchers will have the opportunity to be specifically trained on innovative technologies such as the Quantum Espresso, a useful DFT based tool for calculations at the nanoscale (brief introduction ) and ORCA, a quantum chemistry program suitable for the study of interactions of molecules with 2D materials and its spectral manifestations (detailed view).
     
    Combined with sessions about computational tools, lectures on 2D materials will be given by leading researchers in this field. The workshop also includes an attractive social programme thought to ease the interaction between participants on a cultural, scientific and leisure basis.

    Students will have free registration to the meeting that includes all meals, and will only have to pay for their travel and accommodation. The event is supported by the ICARUS and SOLUTION Consortiums and it will be officially recognized by the University of Burgos under the European Transfer Credit System (number of credits to be approved)

    Due to the limited capacity of the event pre-registration is required. FREE Early Bird Registration deadline: 1st June2019

  • ICARUS M30 team gathering

    On the 9th and 10th of May, 2019 the ICARUS team was gathered in the sunny city of Patras, Greece for its M30 Progress Meeting. The two-day project meeting was hosted by the Laboratory of Technology and Strength of Materials (LTSM) project partners in their premises. Partners, representing the Consortium organizations, met each other in Greece to present the latest scientific and technical achievements, discuss the overall progress of the project, exchange ideas and agree on the latest steps as we are heading towards the end of the project (Augoust 2019).

    The close collaboration between partners will continue online until the end of the project.

  • The ICARUS article included @ the January 2019 issue of the EASN Newsletter, is available for reading

    "An innovative, new predictive tool that allows fast exploration, identification and design of new thermodynamically stable multi-component nanocrystalline (nc) metal alloys with enhanced thermal stability, was developed by the scientists of the ICARUS project. This new tool, namely the High-Throughput Screening (HTS) tool, can be implemented in high-performance computing systems ensuring fast and efficient alloy exploration and selection. In the frame of the project, which aims at discovering an entirely new class of multi-component nc metal alloys resistant to coarsening with properties specifically tailored to application, a systematic exploration for identifying potential thermodynamically stable alloys has been performed with the support of the HTS tool.

    Entering the final semester of its lifetime, ICARUS progresses its pace at research and innovation towards obtaining cutting-edge results. On the 13th and 14th of December, 2018 the ICARUS Consortium conducted its M24 Progress Meeting in Treviso, Italy. The two-day project meeting was an opportunity to discuss on the latest scientific and technical achievements, the overall progress of the project, exchange ideas and agree on next steps.

    We cannot end this article without mentioning the publication of a new open-access scientific paper of our colleague K. Tserpes, under the title “Prediction of mechanical properties of nanocrystalline materials using Voronoi FE models of representative volume element” in the proceedings of the 8th EASN-CEAS International Workshop on “Manufacturing for Growth & Innovation”.
