Description

The morphology of borides grown from the melt in a Ti-Al (Fe, V, B) alloy has been investigated. Flake-like dispersoids are shown by energy dispersive X-ray spectroscopy and electron energy loss boron maps to consist of interleaved titanium boride and B2 grains, with selected area diffraction analysis identifying the boride phase as TiB2. High resolution electron microscopy reveals that the TiB2 and B2 are very high aspect ratio plates, reflecting the overall morphology of the dispersoids, with the interfacial and orientational relationship being {10 bar 10}TiB2//{001}B2 and <0001>TiB2//<010>B2. Growth methods of the TiB2/B2 dispersoids are discussed in light of the surprisingly fine nano-scale of the interleaving plates
