摘要
Fully dense and single-phase Ti3AlC2 bulk ceramic was successfully fabricated by a high energy milling and hot-pressing with Ti, C and Al as starting materials. The details of reaction and phase evolution in high energy milling and hot pressing sintering were investigated. The results show that most of the starting materials transform to Ti-Al intermetallics and TiC in high-energy milling. The as milled powders react into Ti2AlC firstly in hot pressing sintering. When the temperature raise high enough, the Ti2AlC transform to Ti3AlC2. The content of aluminum is higher than that in the theoretical composition, which is attributing to the volatilization of Al at high temperature.
