Cemented carbides with Ni-Co-Cr-Al-W binder phases have been obtained from WC-Ni-Co-Cr3C2-TiAl3 powder mixtures by using standard hardmetal processing routes. Dilatometric and DSC experiments confirm that melting events and shrinkage in these materia

The damage induced by thermal shock in WC-43 vol%Co and WC-40.7 vol%Co-Ni-Cr cemented carbide grades has been analyzed by measuring the loss of fracture strength after repeated water quenching experiments from temperatures ranging from 400 °C to 700

Cemented carbides processed from WC-Ni-Co-Cr3C2-TiAl3 powder mixtures by HIP after sintering present a homogeneous precipitation of gamma prime in their metallic binder phases. Other reaction products include alumina precipitates and (Tix,W 1-x)C mix

Thermal shock damage has been investigated in a WC-6 wt.%Co hardmetal and in a TiMoCN-26 wt.%Ni cermet by measuring their loss of bending strength after repeated quenching in water. The behavior of the hardmetal is significantly better than that of t

The binder phase of WC based cemented carbides has been alloyed by adding two different aluminium compounds, AlN and TiAl3, to mixtures comprised of WC, Ni, Co and Cr3C2 powders. A more efficient alloying effect is obtained by TiAl3 additions likely

Since the major strengthening mechanisms in nanocrystalline bainitic steels arise from the exceptionally small size of the bainitc ferrite plate, accurate determination of this parameter is fundamental for quantitative relating the microstructure to
