Summary

Recent studies have examined new materials that are based on a matrix consisting of a hard carbide phase and an aluminide (e. g., Ni3Al, FeAl) binder phase. Initial results show that these composites have fracture toughness values comparable to the very high values obtained in the best commercial cobalt-bonded WC composites. In addition, these composites can also exhibit extremely high fracture strengths (e. g., in excess of 1 GPa), and these strength levels are retained at temperatures up to 800°C.
