Zusammenfassung:Sintered cemented carbides are described herein exhibiting enhanced high temperature properties without dramatic losses in bending strength. In some embodiments, a sintered cemented carbide composition comprises tungsten carbide, a metallic binder phase comprising at least one metal of the iron group, and at least one solid solution carbide phase comprising tantalum (Ta) and molybdenum (Mo), wherein a value of (Mo/Ta) in the sintered cemented carbide composition is from 0.3-100, and the sintered cemented carbide composition has a transverse rupture strength of at least 4000 MPa.
