N2 - Directional solidification of LaB6-ZrB2, by use of an electron beam heating technique, yielded oriented ZrB2 fibers in a LaB6 matrix. The average diameter of the ZrB2 fibers was ≃0.2-1.2 μm, with fiber lengths up to 100 μm. Primary platelike LaB6 dendrites formed upon the solidification of an ingot with a composition of LaB6-18 wt% ZrB2. LaB6 was the first phase to nucleate when eutectic growth occurred, and ZrB2 showed nonfaceted growth. For the ingot solidified with planar growth the orientation relations of the phases were as follows: growth direction, [001]LaB6∥[00.1]ZrB2; interfacial plane, (11.0)LaB6∥(11.0)ZrB2.
