| Abstract Scope |
Eutectic solidification provides compelling examples of pattern formation, making it a well studied moving boundary phenomenon. However, the formation of several complex eutectic microstructures is still poorly understood, especially in highly anisotropic systems. To investigate the emergence of complex microstructures, we investigate Al-Ge as a model system as one of the phases (Ge) is faceted (f) while the other (Al) is non-faceted (nf). To peer into the real-time growth dynamics of the two eutectic phases at high spatial resolution (~21 nm), we utilize state-of-the-art characterization techniques, namely, synchrotron-based X ray nano-radiography and nano-tomography. Furthermore, we illustrate the crystallographic bias in irregular eutectic solidification through the aid of electron diffraction. These results inform a new growth model of n/nf eutectic solidification. |
