1. Novel powder-coating solutions to improved micro-structures of ZnO based varistors, WC-Co cutting tools, and Co/Ni nano-phase films and sponges
Abstract : Solution chemistry is a versatile and powerful tool in the synthesis of designed, complex nano-level high-tech materials. Normally, the technique is considered too expensive for large-scale production of complex multi-component ceramic materials. READ MORE

2. 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

4. Atomistic modeling of interfaces in WC-Co cemented carbides
Abstract : Grain and phase boundaries are crucial in understanding the properties of real materials. In this thesis, interfaces in WC–Co cemented carbide are modeled atomistically using density functional theory (DFT) and analytic interatomic potentials. READ MORE

5. Microstructure Development of WC-Co Based Cemented Carbides 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 microstructure of two series with different WC grain size was investigated before and after creep deformation using quantitative microscopy, atom probe tomography, and transmission electron microscopy.
