Abstract

Unique properties of BORON CARBIDE (B4C) such as high hardness, low density, and comprehensive area for Neutron attraction, have turned this material into a very suitable candidate for many industrial applications such as nuclear facilities and light armored plates. According to inappropriate sinter ability of BORON CARBIDE, phenolic resin was utilized as sintered help for this ceramic. Different free additive samples of B4C with 5wt% phenolic resin were prepared and sintered at 2200°C. Then their physical and MECHANICAL PROPERTIES were investigated. Results show that the relative density of samples including 5wt% phenolic resin is equal to %95 and for samples without additive is equal to %82 of theoretical density. Furthermore, it can be seen an improvement in MECHANICAL PROPERTIES in comparison of free additives samples; so that the flexural strength from 264 to 318MPa, the modulus of elasticity from 445 to 465GPa, Vickers hardness from 3020 to 3150GPa and fracture toughness from 2.6 to 4.2MPa.m1/2 will be improved.
