Influence of Fe/Ni/Al additive on the sintering behaviors of TiB2 cermets
Fe-Ni-Al mixtures as hot-pressing sintering additive to Titanium diboride (TiB 2 ) were studied. It is found that liquid alloy formed under high temperature hardly has effects on the densification behaviors of TiB 2 -independent. Fe-Ni-Al additive just works as filler between TiB 2 particles and doe...

particles. Multiple-steps pressing mode will give more time and space for the liquid flowing and improve the relative density of TiB
