Abstract: Herein, synchrotron‐generated high‐energy X‐ray is used to study growth behavior at the liquid–solid transition of multicomponent alloys during in situ directional solidification experiments at Deutsche Elektronen‐Synchrotron (DESY), Hamburg, Germany. The unique “FlexiDS” sample environment is… read more here.

DOI: 10.1016/j.actamat.2018.02.034
Abstract: Abstract Metastable Sn-NiSn4 eutectic can form in electronic solder joints and is a reliability concern. Here the competition between stable Sn-Ni3Sn4 and metastable Sn-NiSn4 eutectic growth is studied during unidirectional solidification. The stable and metastable… read more here.

DOI: 10.1016/j.jeurceramsoc.2020.03.025
Abstract: Abstract Structural features of Al2O3-YAG-ZrO2:Y eutectic plates grown by the EFG process have been studied. X-ray tomography shows that all three phases are continuous along the whole sample, suggesting a fully coupled ternary eutectic growth.… read more here.

DOI: 10.1103/physreve.97.053302
Abstract: The influence of natural convection on lamellar eutectic growth was determined by a comprehensive phase-field lattice-Boltzmann study for Al-Cu and CBr_{4}-C_{2}Cl_{6} eutectic alloys. The mass differences resulting from concentration differences led to the fluid flow… read more here.

DOI: 10.1177/1464420718784314
Abstract: The dependences of microstructures on the solidification thermal parameters of Sn–0.5 wt.%Cu, Sn–0.5 wt.%Cu–0.05 wt.%Al, and Sn–0.5 wt.%Cu–0.1 wt.%Al alloys are examined. Ranges of sizes and morphologies of microstructural phases have been quantitatively assessed due to the broad spectra of… read more here.
