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

Rethinking how cold spray really bonds dissimilar metals

~ Matheus A. Tunes ~ Leave a comment

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

A milestone for Ti-based alloys in additive manufacturing

~ Matheus A. Tunes ~ 1 Comment

In a great and recent work from my friend Christian Fleißner-Rieger -- doctoral researcher at Montanuniversität Leoben (Austria) -- has shown the discovery of a new and soft martensitic phase in a Ti-based model alloy obtained via additive manufacturing. Such a soft martensitic phase -- which the nucleation can be controlled via processing parameters -- … Continue reading A milestone for Ti-based alloys in additive manufacturing
