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

In a great and recent work from my friend Christian Fleißner-Rieger -- doctoral researcher at Montanuniversität Leoben (Austria) -- has shown the discovery of a new and soft martensitic phase in a Ti-based model alloy obtained via additive manufacturing. Such a soft martensitic phase -- which the nucleation can be controlled via processing parameters -- … Continue reading A milestone for Ti-based alloys in additive manufacturing
A modified version of the well-known Cantor's alloy, the nanocrystalline CoCrCuFeNi high-entropy alloy was subjected to heavy-ion irradiation in situ within a TEM in our most recent study within the field of potential new nuclear materials. The stability of the alloy was investigated in a broad range of irradiation doses and temperature, revealing the nucleation … Continue reading Discovery of FeCo nanomagnets under irradiation in a high-entropy alloy
From Montanuniversität Leoben: https://www.unileoben.ac.at/en/newsdetail/schluessel-zum-recycling For almost a century, commercial aluminum materials have been developed and optimized for high performance in specific applications within strict chemical confines of industrially established alloy classes. The requirements associated with sustainable lightweighting concepts call for new strategies that offer a broader property portfolio with a better trade-off between formability, achievable … Continue reading Key to recycling
