Functionally graded cemented carbides (FGCCs) have an excellent combination of high hardness and high toughness, and the mechanical properties are strongly influenced by the graded structures. In this work, the effects of the addition of Y 2 O 3 on the microstructures and mechanical properties of FGCCs were studied. The FGCCs were prepared by pre-sintering and carburizing of carbon-deficient...
