The solar system as a new frontier for materials at extremes

~ Matheus A. Tunes ~ Leave a comment

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

Metal alloy “hides” magnetic material with potential to enhance electronic devices

~ Matheus A. Tunes ~ Leave a comment

Despite their diminutive size, iron and cobalt nanoislands have strong magnetism, which can increase storage and data transfer capacity. Original story by Jornal da USP. Published: 01/10/2022  Updated: 01/11/2022 at 16:52 By Júlio Bernardes Researchers have evaluated the radiation resistance of highly concentrated metal alloys for use in nuclear reactors and have identified materials with … Continue reading Metal alloy “hides” magnetic material with potential to enhance electronic devices

A milestone for Ti-based alloys in additive manufacturing

~ Matheus A. Tunes ~ 1 Comment

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

Discovery of FeCo nanomagnets under irradiation in a high-entropy alloy

~ Matheus A. Tunes ~ 1 Comment

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
