摘要：

The microstructural characteristics of the bulk Ti3AlC2 ceramic, synthesized by a solid-liquid reaction and simultaneous in-situ hot pressing, have been studied by electron diffraction and high-resolution transmission electron microscopy. It was found that the as-synthesized ceramic is fully dense and free from amorphous phase at the grain boundaries. The ceramic is predominantly a single phase of hexagonal Ti3AlC2 with a minor volume of tetragonal Al3Ti and cubic TiC. The Al3Ti grains are crystallographically independent of the Ti3AlC2, whereas TiC is intergrown with Ti3AlC2, forming thin platelets and maintaining a close orientational relationship with the Ti3AlC2 matrix.
