Using the Plasma FIB as a revolutionary tool for studying radiation effects in solids: cover page award!

~ Matheus A. Tunes ~ 4 Comments

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!

Nanocrystalline lightweight alloys for space exploration

~ Matheus A. Tunes ~ Leave a comment

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

Further improving the corrosion resistance of Al-based alloys for aerospace applications with Cr-free treatments

~ Matheus A. Tunes ~ Leave a comment

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

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
