Revolutionary Findings in Nonferrous Metallurgy for Fusion Technology

~ Matheus A. Tunes ~ Leave a comment

03/20/2025 The [X-MAT] research team from the Chair of Nonferrous Metallurgy, in collaboration with international partners, has made a significant breakthrough in the development of radiation-resistant materials for nuclear fusion reactors. Their latest study, published in Advanced Science (DOI: 10.1002/advs.202417659), challenges conventional high-entropy alloy (HEA) concept by demonstrating that reduced chemical complexity can still achieve … Continue reading Revolutionary Findings in Nonferrous Metallurgy for Fusion Technology

Investigating Hydrogen Embrittlement to Develop Superior Functional Alloys – Prof. Dr. Livia C. Malheiros (UK)

~ Matheus A. Tunes ~ Leave a comment

Hydrogen embrittlement (HE) remains a critical challenge in materials engineering, particularly for industries reliant on high-performance metals, such as energy and transportation. As hydrogen atoms diffuse into metals, they weaken the material’s structural integrity, leading to reduced load-bearing capacity and increased brittleness. A deeper understanding of hydrogen’s interactions with metal lattice structures, defects, and stress … Continue reading Investigating Hydrogen Embrittlement to Develop Superior Functional Alloys – Prof. Dr. Livia C. Malheiros (UK)

The demand for sustainable metal production is driving innovation in aluminium recycling. The new preprint of our group led by Dr. Sebastian Samberger is available and it is entitled Impurity-Induced Phase Transformations in AlMgZn(Cu) Crossover Alloys: Pathways to Enhance Recycling Content and Processability. Dr. Samberger explores how Fe/Si ratios and cooling rates influence phase transformations and … Continue reading Upscaling and Recycling of Aluminium Alloys

The last set of images taken by Voyager 1 spacecraft

~ Matheus A. Tunes ~ Leave a comment

A fascinating research paper recently caught my attention: it documents the final images captured by the Voyager 1 spacecraft before its cameras were permanently shut down. While the images themselves are breathtaking, what truly stood out to me was the incredible effort behind protecting the spacecraft from radiation damage as it ventured farther from the … Continue reading The last set of images taken by Voyager 1 spacecraft

A great scientific debate: Are clusters or Guinier-Preston zones responsible for strengthening an Al-Cu-Mg alloy?

~ Matheus A. Tunes ~ Leave a comment

Feature image credits: https://www.scienceisweird.com/arguing-comics Science thrives on debate, and the historic clash between Ringer et al. and Zahra et al. over the role of solute clustering in Al-Cu-Mg alloys is a perfect example of how scientific disputes drive progress. In this case, one side argued that Cu-Mg clusters were a distinct strengthening mechanism, while the … Continue reading A great scientific debate: Are clusters or Guinier-Preston zones responsible for strengthening an Al-Cu-Mg alloy?
