摘要：
The microstructure of TiB2-Ti (CN)-Ni ceramics has been investigated by means of transmission and analytical electron microscopy. In many cases, TiB2 and Ti(CN) grew together with a unique orientation relationship. However, Ti(CN) particles were also found to precipitate in TiB2 crystals, and a different orientation relationship between precipitated Ti (CN) particles and TiB2 crystals can be detected. The TiB2/Ti(CN) interface was investigated using high-resolution electron microscopy. During hot-press procession, two Ni-rich intergranular phases with N31Si12 and N16Ti6Si7 type structures and amorphous phase were formed on grain boundaries.
