Abstract Modifications of the binder phase ( γ ) cemented carbides have potential to increase hardness and wear resistance whole material. Partially, coherent precipitations with L1 2 structure (γ’) promise these improved properties without sacrificing tensile strength or toughness. ’ is a metastable in Al–Co–W ternary system form Co 3 (Al,W) which stabilized by substitution cobalt nickel. Supe...

We prepare multi-component transition monocarbides of chosen composition by arc-melting together a pre-alloy the metals and cast iron. Based on elements Ti, Ta, V, Nb W, 51 different binary, ternary quaternary compositions are produced. The intrinsic hardness H modulus E resulting iron-embedded carbide particles directly measured using nanoindentation. Of all tested here WC shows highest while ...

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...
