New insight from CEMAS 📷
Using HRSTEM HAADF imaging, researchers can see the nucleation of a complex carbide within a microtwin in the fcc matrix of an additively manufactured Ni‑based superalloy. Postdoc Andreas Bezold was able to capture this image on CEMAS' Themis Z S/TEM.

Happy #MicroscopyMonday 🔬 Here is a HRSTEM HAADF micrograph captured by Bryan Crossman, showing a low-angle grain boundary (LAGB) in a BCC Ta₅₅Re₄₅ (at.%) refractory alloy. This boundary is primarily a tilt boundary, formed by a ~12.6° rotation about the [001] zone axis.

These experiments were performed by graduate student Rogine Gomez in the Leonard research group in MSE with CEMAS Senior Research Associate Daniel Veghte. Recrystallization and growth are observed from the heavily deformed areas (initially non-indexable areas).

The paper demonstrated that alloying Mg with Ca shows promise in weakening deformation and recrystallization texture that can be associated with increased ductility and formability.

Check out the research SEM image that turned out unexpectedly artistic when a mouse appeared, taken by graduate student Nicole Hudak! Captured on Apreo 1/2 using standard conditions, it’s a BSE image of a titanium alloy. It takes a bit of imagination to see the tiny creature 🔬

What appear to be the “ears” are actually regions outlined by colloidal silica left behind during polishing and final cleaning. The “eye” is a void, and the rest of the “mouse” takes shape along the alloy’s grain boundaries.
