T1 - Effect of carbon content on the microstructure and mechanical properties of NbC-Ni based cermets JF - Metals N2 - The aim of this work was to correlate the overall carbon contents in NbC-Ni, NbC-Ni-VC and NbC-Ni-Mo starting powders with the resulting microstructure, hardness, and fracture toughness of Ni-bonded NbC cermets.

A1 - Woydt, Mathias T1 - NbC-based cermets: influence of secondary carbide addition and metal binder T2 - Proceedings of the International Symposium on Wear Resistant Alloy for the Mining and Processing Industry N2 - Full densification of Fe, Co and Ni bonded NbC based cermet’s was achieved by pressure less liquid phase sintering in vacuum for one hour at 1420°C. The hardness and toughness of the NbC matrix cermet’s can be mainly tailored by the binder composition and secondary carbide additions. Ni binder based NbC cermet’s allow the combination of high hardness and improved toughness. The addition of lesser amounts of VC/Cr3C2 in a NbC partially substituted WC-Co cemented carbide increased significantly the hardness in combination with a moderate fracture toughness.
