Abstract

A liquid-metal quenching method is designed for studying the rapid solidification behavior of oxide eutectic composites. The lamellar spacing of an Al₂O₃/Y₃Al₅O₁₂ eutectic nanocomposite processed using this method is only 50 nm, which is an order of magnitude smaller than that reported previously. Results from the microstructural characterization of the resulting materials are described. Using the classical eutectic growth model, the relative solidification rate in this method is calculated to be 1.88 × 10^-2 m s^-1.
