Abstract

The objective of the present investigation was to study the effect of TiB2 addition on sintering behavior and mechanical properties of pressureless-sintered B4C ceramic. Different amounts of TiB2, mainly 5 t0 30 wt.% were added to the base material. Pressureless sintering was conducted at 2,050 and at 2,150 °C. Addition of 30 wt.% TiB2 and sintering at 2,150 °C resulted in improving the density of the samples to about 99% of theoretical density. The composite samples exhibited very good mechanical properties (hardness, flexural strength and fracture toughness). As the amount of TiB2 was increased further, the mechanical properties were reduced, except for the fracture toughness, apparently due to too much TiB2 in the specimen.
