On the 3D printing of novel aluminium crossover alloys

~ Matheus A. Tunes ~ Leave a comment

Aluminium crossover alloys are one of the more interesting recent developments in light metals. Rather than staying within the traditional wrought families, they deliberately blend the chemistries of the AA5xxx and AA7xxx systems, and in doing so they form the compositionally complex T-phase, Mg32(Al,Cu)49, which gives a remarkable hardening response and has already attracted serious … Continue reading On the 3D printing of novel aluminium crossover alloys

Prof. Gerhard Sperl: a lifetime connecting metallurgy’s past and present

~ Matheus A. Tunes ~ Leave a comment

There are scientists whose work is best understood through instruments, and there are those whose work is best understood through time. Gerhard Sperl – who passed away on Easter Monday, 5 April 2021, at the age of 84 — belonged firmly to the second kind, though he was thoroughly at home with the first. Born … Continue reading Prof. Gerhard Sperl: a lifetime connecting metallurgy’s past and present

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
