Iron aluminides as an alternative binder for cemented carbides: A review and perspective towards additive manufacturing

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 investigated issues W raw material availability. Additionally, manufacturing carbides is moving towards Additive Manufacturing (AM) a feasible technology production complex net shape parts compared conventional methods. summarizes in detail aluminide based produced powder metallurgy methods, well next step up AM technologies.
