This review focuses on the potential advantages of iron aluminides as an alternative binder for cemented carbides, by means thermodynamics, microstructure, mechanical properties, corrosion and oxidation resistance. Iron have been identified binders WC-Co. Actually, new composite materials free Co are under development due to environmental safety healthcare concerns, substitutes WC being investi...

Cemented carbides, or hard metals, are ceramic–metal composites usually consisting of tungsten carbide particles bound by a cobalt-based alloy. They the backbone materials for tooling industry, as direct consequence outstanding range property combinations, depending on their effective microstructural assemblage, i.e., physical dimensions and relative content constitutive phases. Hence, reliable...

Tungsten carbide (WC) is the most important tungsten compound, and main component of WC-Co cermet composites. are widely used engineering materials due to combination high hardness strength with toughness plasticity metallic binder. The direct synthesis WC from concentrate containing ∼70% WO3 has been achieved by carbothermic reduction. Mineral/carbon black mixtures were prepared planetary ball...
