These images, generated from scanning electron microscopy, show the grain structures and crystal lattice orientations of (A) CrMnFeCoNi and (B) CrCoNi alloys. (C) and (D) show examples of fractures in CrCoNi at 293 K and 20 K, respectively. (Source: Robert Ritchie/ Berkeley)

Say hello to the toughest alloy on earth

Scientists have measured the highest toughness ever recorded, of any material, while investigating a metallic alloy made of chromium, cobalt, and nickel (CrCoNi). Not only is the metal extremely ductile — which, in materials science, means highly malleable — and impressively strong, its strength and ductility improve as it gets colder. This runs counter to most other materials in existence.

Automated surface smoothing and homogenization of 3D printed components

When it started offering ready-to-install 3D printed plastic and metal components to its customers, the job shop Klaus Stöcker metal processing initially utilized manual post processing methods. Because of the growing demand and stricter requirements of the post processing operation, the company purchased the automated systems S1 for de-powdering and M1 for the surface smoothing and homogenization from AM Solutions.

Faster tooling through 3D printing

Whether injection moulding or machining, tooling is essential. Cheaper production and cooling close to the contour are the main arguments for producing tools using additive manufacturing. But there is more to it than that.
