11. Computational investigation of interface structure and composition in cemented carbides at finite temperatures
Abstract : WC-Co cemented carbides combine superb hardness with high toughness making them ideal for usage in high-speed machining of steels and in wear resistance tools. These excellent mechanical properties are to a large extent dependent on the microstructure and thus the interfacial properties of the material. READ MORE

12. 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.

13. ICME guided development of cemented carbides with alternative binder systems
Abstract : The development of alternative binder systems for tungsten carbide (WC) based cemented carbides has again become of relevance due to possible changes in EU regulations regarding the use of Cobalt (Co). A framework for the ICME (Integrated Computational Materials Engineering) based Materials Design is presented to accelerate the development of alternative binder systems. READ MORE

14. Evolution of WC-Co cemented carbide microstructure during creep testing
Abstract : The aim of this work is to understand the mechanisms behind the plastic deformation of WC-Co based cemented carbides. The microstructures of two materials have been investigated before and after creep deformation using quantitative microscopy, atom probe tomography, and transmission electron microscopy. READ MORE

15. Microstructural aspects on wear of cemented carbides
Abstract : Cemented carbides are known to be very wear resistant and are therefore often usedin applications involving surface damage and wear. The work presented hereinvestigates the coupling between the microstructure and some fundamental wearand deformation mechanisms typical for cemented carbides. READ MORE
