Microstructure and Mechanical Properties of TiB2/FeMo Cermet

Abstract

Abstract: TiB₂cermet containing 7wt% Fe and 3wt% Mo was fabricated by hot pressing. The effects of sintering temperature, holding time on microstructure and mechanical properties were investigated, the densifacation process during sintering was analysed. The experimental results show that the bending strength and the Rockwell hardness reveal a peak value with the sintering temperature rising up; with holding time prolonged, the bending strength decreases slightly. The densification rate is the fastest in the rearrangement stage during liquid sintering.

Key words: cermet, densification, hot pressing, microstructure
