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

A milestone for Ti-based alloys in additive manufacturing

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
