Abstract
Abstract
In this paper, B-Al-Ti-C system ceramics were fabricated by plasma activated sintering(PAS) technique. The final sintered products consisted mainly of AlB12C2 and TiB2. The specimens could be densified at the temperature of 1460 °C∼1600 °C, which is near 400 °C lower than the dense pure AlB12C2 and TiB2 ceramics. The sintered samples are nearly fully dense, and there are substantially no pores observed by observing the SEM photograph. The mechanism of low temperature densification and the phenomenon of varied specimens during sintering were explained in details in this study.
