Abstract

Detail microstructure of LaB₆-ZrB₂ composites has been characterized by TEM and HRTEM. The directionally solidified ZrB ₂ fibers in LaB₆ matrix near LaB₆-ZrB ₂ eutectics present at least three growing relationship systems. In addition to previous report of [001]LaB₆ / [0001]ZrB₂ relationship, [0 1̄ 1]LaB₅ / [001]ZrB₂ and [1 2̄ 0]LaB₆ / [0001]ZrB₂. were identified. Different with [001]LaB₆ / [0001]ZrB₂ system, the interfaces of [0 1̄ 1]LaB₆ / [0001]ZrB₂ and [1 2̄ 0]LaB ₆ / [0001]ZrB₂. show non-coherent and clean interfaces. There is neither glassy phase nor reaction products found at the interfaces.
