Rethinking copper metallurgy for the future of fusion reactors

~ Matheus A. Tunes ~ 2 Comments

We are delighted to share a new preprint that takes on one of fusion energy's most stubborn materials problems: building a heat sink that can survive inside a reactor. Commercial fusion demands components that withstand intense neutron bombardment while extracting punishing heat loads for conversion to electricity, and CuCrZr — a copper alloy strengthened by … Continue reading Rethinking copper metallurgy for the future of fusion reactors

A new way to “see” inside aluminium alloys

~ Matheus A. Tunes ~ Leave a comment

What if a single microscope image could simultaneously show nanoclusters, dislocations, grain boundaries, and corrosion pores – all in under a minute? We have found a way to do exactly that and we described recently in a paper published it in Small Methods! The method, called differential phase contrast (DPC), is not new to electron … Continue reading A new way to “see” inside aluminium alloys

New Preprint: Unlocking Nanoscale Detail in Aluminium Alloys with DPC Segmentation

~ Matheus A. Tunes ~ Leave a comment

We are pleased to share our latest preprint, now available on arXiv: Unlocking nanoscale microstructural detail in aluminium alloys through differential phase contrast segmentation in STEM (arXiv:2603.11643). In this work, we show how differential phase contrast (DPC) imaging in scanning transmission electron microscopy can be turned into a powerful, quantitative tool for characterising the microstructures … Continue reading New Preprint: Unlocking Nanoscale Detail in Aluminium Alloys with DPC Segmentation

Pushing the Limits of Aluminium Crossover Alloys

~ Matheus A. Tunes ~ Leave a comment

Dr. mont. Patrick Willenshofer’s recent publication, “Influence of alloy chemistry and overaging on mechanical properties and corrosion resistance in aluminium crossover alloys”, is a remarkable contribution to the rapidly evolving field of advanced aluminium alloy development. This paper investigates the nuanced interplay between alloying elements and thermal history in novel AlMgZn-based crossover alloys enriched with copper … Continue reading Pushing the Limits of Aluminium Crossover Alloys

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?
