Paper 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 to 30wt% were added to the base material. Addition of 30wt% TiB2 and sintering at 2050°C resulted in improving the density of the samples to about 98.5% of the theoretical density. The composite samples exhibited very good mechanical properties (hardness, flexural strength and fracture toughness). As the amount of TiB2 was increased from 15 to 30, the mechanical properties were reduced, except for the fracture toughness, apparently due to excess amount of sintering aid in the specimen.
