On the 3D printing of novel aluminium crossover alloys

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

Rethinking how cold spray really bonds dissimilar metals

Cold spray sounds almost too simple to work: fire a metal particle at a surface fast enough, and it sticks – no melting, no welding, just brute plastic deformation smashing a bond into place. That has been the textbook story for two decades. But in our latest paper with colleagues at Politecnico di Milano and … Continue reading Rethinking how cold spray really bonds dissimilar metals

Folding, thinner, lighter, and stronger wings signals a quiet retreat for aluminium in aerospace

Airbus has just announced the next phase of its Wing of Tomorrow programme: a three-year flight-test campaign, unveiled at Farnborough, that will bolt full-scale wing extensions onto an A321neo to trial the longer, higher-aspect-ratio wings destined for the successor to its best-selling single-aisle family. The extensions are several metres long and stand in for a … Continue reading Folding, thinner, lighter, and stronger wings signals a quiet retreat for aluminium in aerospace

The Spirit of Metallurgy at 75 Years Strong

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

Andreas Weidinger: Pushing the Boundaries of Aluminium Alloy Research

We are thrilled to spotlight the remarkable work of Andreas Weidinger, a doctoral researcher in the Chair of Nonferrous Metallurgy at Montanuniversität Leoben. Currently a visiting scholar at Chalmers University in Sweden, Andreas is making waves in the Swedish lands with his innovative research on aluminum alloys. His groundbreaking work with 5/7 crossover aluminum alloy … Continue reading Andreas Weidinger: Pushing the Boundaries of Aluminium Alloy Research
