Abstract

A detailed investigation of the effect of alumina diluent on the Al2O3-TiB2/ZrB2 composite by self propagating high temperature synthesis (SHS) dynamic compaction was carried out. A dense composite could be obtained and microstructure could be tailored and controlled by adding alumina as diluent during the SHS reaction. The microhardness values decreased for 5 and 10 wt pct additions of alumna but increased for 15 and 20 wt pct additions. Hardness is influenced by the different phases present and the grain size.
