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

The Spirit of Metallurgy at 75 Years Strong

~ Matheus A. Tunes ~ Leave a comment

Professor Peter J. Uggowitzer was never officially my mentor or supervisor -- neither during my studies nor in my former postdoc in Leoben. Yet, his presence and friendship over all these years have profoundly shaped both my personal and professional life. Through him, I learned not just metallurgy, but how to think metallurgy -- how … Continue reading The Spirit of Metallurgy at 75 Years Strong

Dr. Aster’s Breakthrough in Aluminium Alloy Design with Cluster-Hardnening

~ Matheus A. Tunes ~ Leave a comment

In his recent work, Dr. Philip Aster delivers a remarkable contribution to the understanding of microstructural evolution in Al-Mg-Zn-Cu crossover alloys, with a particular focus on the role of copper in long-term aging (LTA) conditions. Through advanced atom probe tomography (APT), Dr. Aster demonstrates how Cu additions not only promote finer clustering and T-phase precursors … Continue reading Dr. Aster’s Breakthrough in Aluminium Alloy Design with Cluster-Hardnening
