We investigate the radiation response of a hard refractory high entropy carbide (HEC): the (CrNbTaTiW)C. Comparison with the high entropy alloy (HEA) has shown the HEC outperforms the HEA under irradiation. Results suggest high-entropy ceramics can be alternative to HEAs in extreme environments. Available now at Acta Materialia (open access)! Do not forget to see … Continue reading Novel high entropy ceramics for extreme environments
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
Our recent work entitled "Rethinking radiation effects in materials science using the plasma-focused ion beam" published in the September issue of the historically prestigious Journal of Materials Science (Springer) has been awarded the cover page of the November 2022 issue (volume 57, number 41). A very nice editorial has been written by Professor C. Barry … Continue reading Using the Plasma FIB as a revolutionary tool for studying radiation effects in solids: cover page award!
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
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
I just wanna share with you guys a recent publication from friends, arising as another international collaboration, where the sustainability of aluminum alloys and plans for the future in the field have been nicely outlined! Great work coordinated by Professors Dierk Raabe and Stefan Pogatscher! https://www.sciencedirect.com/science/article/pii/S0079642522000287
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
