Abstract

Although B₆0 materials have shown excellent potentials for wear resistant and cutting tool applications, the problem of low fracture toughness and the difficulties to densify has delayed the application of B₆0 materials in the industry. In this work, efforts have been directed towards improving the fracture toughness and densification of these materials by incorporating suitable secondary phases and tailoring the microstructure to the desired properties. Synthesized B₆0 was hot pressed at 1850°C and 80 MPa in an argon environment, with nickel compounds (nickel (Ni) and nickel oxide (NiO)). The addition of 1.10 vol.% of additives improved the densification of the B₆0 powders in comparison to the pure B₆0 material. The fracture mode observed in the sintered materials is mainly transgranular.
