Faster cooling after sintering or the heat-treatment like brazing and high temperature joining can cause the formation of the layers of free carbon at the carbide–binder interface of the WC based cemented carbides. Formation of the free carbon laye

Hardness of WC–Ni cemented carbides with tiny addition of TiC is studied. The addition of TiC changes the shape of WC crystals to a flatter triangular prism with lower value of the shape equiaxiality PWC. The hardness increases 8–15% on the alloy

Equilibrium and geometry models for the contiguity of carbide crystals in cemented carbides are discussed. The equilibrium approach is applicable to rounded carbide crystals with a sufficient amount of the binder phase. Increase of the angularity of

Hardness and Deformation of Hardmetals at Room Temperature

Autor: S. A. Firstov, A.V. Shatov, S.S. Ponomarev

Hardness, elastic moduli and deformation behavior of hardmetals at room temperature are reviewed. The state of the art for the structure-property relations that are based on various chemistries, geometries, residual stresses and defects of the micros
