In a new pre-print available at SSRN Electronic Journal, Samberger et al. introduce a new concept for fine-grained aluminium alloys. The authors shows a process of synthesis that resulted in a fine-grained aluminium crossover alloys intended to be applied in high-temperature forming processes. The use of EBSD unravels the active role of T-phase precipitates on … Continue reading Advancing the field of fine-grained aluminium alloys
Can Ti-based MAX phases -- this new class of potential functional materials -- be applied in future nuclear reactors? We investigated the response of Ti-based MAX phases to both neutrons and heavy ions. The discoveries of this intense decade-long research has just been published at Materials Today Energy. Open access article access here: https://doi.org/10.1016/j.mtener.2022.101186
We continue in our saga aiming at finding better radiation-resistant materials for applications in the extreme environment of the solar system. I am delighted to introduce you our new paper that was led by Patrick Willenshofer (another genius from Montanuniversitaet Leoben). In this paper, we introduce a revolutionary nanocrystalline crossover aluminium alloy that scored the … Continue reading Nanocrystalline lightweight alloys for space exploration
With great pleasure I would like to share our most recent paper, which just got published at the Journal of Materials Science, edited by Professor C. Barry Carter. In this new article, we present an innovative methodology to rethink the way we investigate radiation effects in materials science: by using the Plasma Focused Ion Beam … Continue reading Rethinking Radiation Effects in Solids
A great and highly innovative work by Dr. Philip Dumitraschkewitz demonstrates the use of MEMS-based technology for controlling/manipulating microstructures of eutectic alloys at the nanoscale. Available now at Acta Materialia!
A great paper and research led by my friend Oscar M. Prada Ramirez recently shows that the corrosion resistance of aerospace grade Al-based alloys can be significantly improved using Ce-nanoparticles in an anodization treatment using tartaric-sulfuric acid environments! The aluminium alloy series 2xxx with its anodic layer filled with Ce nanoparticles! A pathway to reduce … Continue reading Further improving the corrosion resistance of Al-based alloys for aerospace applications with Cr-free treatments
Just sharing with you friends a very interesting research article led by my friend and co-worker, Professor Yanwen Zhang, on the role of electronic energy loss in HEAs. We also do very nice comparison with ceramics! Online now at Current Opinion in Solid State and Materials Science, Elsevier! https://www.sciencedirect.com/science/article/pii/S1359028622000213
Sharing my new seminar slides with the community on the challenges to design and evaluate new materials for extraterrestrial applications! This research has been only possible via an international collaboration with the brilliant metallurgy minds present at the Montanuniversität Leoben! Super interesting new works coming very very soon! Available at the ResearchGate! (LA-UR-22-23107) https://www.researchgate.net/publication/359771021_The_solar_system_as_a_new_frontier_for_materials_at_extremes
The Parker Solar Probe just encountered an intense energetic particle radiation stream on its way to the Sun. A beautiful video from NASA! Particle irradiation emitted by the Sun's and its effects on functional metallic alloys it is one of our most important research fields nowadays. https://www.youtube.com/watch?v=IQXNqhQzBLM
