1. Cemented Carbide Sintering : Constitutive Relations and Microstructural Evolution
Abstract : Cemented carbides based on tungsten carbide and cobalt arecommonly produced by a powder metallurgy route including liquidphase sintering. The pressed compact densifies to almost halfits volume during sintering due to pore elimination. READ MORE

2. WC grain growth during sintering of cemented carbides : Experiments and simulations
Abstract : Cemented carbides are composite materials consisting of a hard carbide and a ductile binder. They are powdermetallurgically manufactured, where liquid-phase sintering is one of the main steps. The most common cemented carbide consists of WC and Co and it is widely used for cutting tools.

4. Microstructure of Cermets
Abstract : The microstructure of several TiC-TiN-Mo2C-WC-Co/Ni model alloys and a commercial (Ti,Ta,W,Mo)(C,N)-(Co,Ni) type cermet was studied using x-ray diffraction, optical microscopy, scanning electron microscopy, analytical electron microscopy and atom probe field ion microscopy. In addition thermodynamical calculations were made in order to understand the development of the microstructure during sintering. READ MORE
