Time‐Efficient Columnar‐to‐Equiaxed Transition via High Magnetic Field Processing

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT The need to simplify processing routes and improve processing efficiency motivates the development of time‐efficient methods for inducing the columnar‐to‐equiaxed transition (CET) during solidification while tailoring material performance. Conventional multistep CET approaches are time‐consuming and often struggle to simultaneously regulate ...

In Situ Heating STEM of the Thickness‐Dependent Evolution of Ferroelastic Domains

Small, Volume 22, Issue 50, 7 September 2026.
In‐situ heating scanning transmission electron microscopy combined with machine‐learning segmentation is used to study the thickness and temperature dependent behavior of ferroelastic domain walls in free‐standing LaAlO3 samples. The results quantify domain wall curvature and density throughout cooling, revealing a pronounced thickness‐dependent ...
