Tuesday publication post! 📖 In this newest publication, researchers used the #FusionAX system to directly observe the atomic-scale phase transformations and diffusion mechanisms in Cu-Zn alloys during heating using high resolution in situ TEM.
Cu-Zn alloys are widely used in electrical and structural applications due to their excellent conductivity and mechanical strength. Understanding how their microstructure evolves under thermal conditions is essential for improving their long-term performance and stability.
Key findings:
🔥 Direct observation of the transformation from Zn/Cu thin films to β-CuZn at 180 °C.
⚛️ Identification of the epitaxial relationship between β-CuZn and the Cu substrate during phase formation.
🔬 Formation of the Cu-rich α phase at 300 °C through layer-by-layer atomic diffusion, reducing the system’s Gibbs free energy.
📊 Atomic-resolution imaging provides new insight into the kinetics and mechanisms governing phase evolution in Cu-Zn alloys.
This work highlights how #FusionAX enables researchers to visualize atomic-scale structural transformations in real time and at high temperature, providing valuable insights on thermal stability and mechanical performance.
