Abstract

LaB₆-ZrB₂ eutectic composites were grown by the floating zone technique using electric arc fusion and electron bombardment methods. Well-oriented microstructures were obtained in the central part of the specimens by these two methods. Bead ripple pattern occurred in the outer layer of the specimens prepared by electric arc fusion, and a ZrB₂ depletion layer developed in the surface of the specimens prepared by electron beam melting. No microstructural coarsening was observed after annealing the specimens at 1650°C in N₂ for 100 h.
