Transforming the Aluminum Industry through Recycling

~ Matheus A. Tunes ~ Leave a comment

In the pioneering work of PhD student Sebastian Samberger, the spotlight shines on aluminum recycling as a beacon of sustainability within the metals industry. Samberger's thorough analysis underscores the significant environmental challenges posed by the primary production of aluminum, including high energy consumption and CO2 emissions from non-renewable energy sources. Through his research, Samberger eloquently … Continue reading Transforming the Aluminum Industry through Recycling

Consolidating nanocrystalline aluminium crossover alloys for extreme environments

~ Matheus A. Tunes ~ Leave a comment

We are re currently exploring nanocrystalline aluminum alloys to understand how they perform in extreme conditions such as energetic particle irradiation and high temperatures. Aluminum alloys are ideal for challenging environments, given their versatility, lightweight nature, and favorable properties. In a recent preprint led by Patrick Willenshofer, we discovered and reported for the first time … Continue reading Consolidating nanocrystalline aluminium crossover alloys for extreme environments

Maximizing corrosion resistance of aerospace aluminium with self-healing coatings

~ Matheus A. Tunes ~ Leave a comment

The use of sol-gel coatings to increase the corrosion resistance of commercial aerospace aluminium alloys is the topic of our most-recent paper at Corrosion Science. In combination with anodization treatment and the use of Ce nanoparticles to fill-in the pores of the anodic layer, we have observed that a post-treatment with sol-gel coatings further increases … Continue reading Maximizing corrosion resistance of aerospace aluminium with self-healing coatings

Advancing the field of fine-grained aluminium alloys

~ Matheus A. Tunes ~ Leave a comment

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

The British science magazine New Scientist -- a world-class prestigious publisher of scientific news communication -- is bringing a very interesting story coverage on our recent preprint "Radiation-resistant aluminium alloy for space missions in the extreme environment of the solar system". In their article entitled "Aluminium alloy could boost spacecraft radiation shielding 100-fold", Alex Wilkins … Continue reading NewScientist highlights our work on Space Materials

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
