2. Effect of microstructure on toughness characteristics of cutting materials
University essay from KTH/MaterialvetenskapAbstract : Improved fracture toughness at a given strength level is one of the most important properties of cemented carbides. Large number of different testing methods (both theoretical and experimental) has been proposed to determine fracture toughness of cemented carbides and it has been always a topic of interest to relate fracture toughness with mechanical properties.

3. Edge effect on abrasive wear mechanisms and wear resistance in WC-6wt.% Co hardmetals
University essay from Institutionen för ingenjörsvetenskap, fysik och matematikAbstract : Wear of hardmetals is a complicated topic because the wear resistance and the wear mechanisms are influenced by microstructural factors. Although edge wear resistance has a vital importance, most of the researches made in laboratories are related to flat wear resistance using coarse abrasive paper. READ MORE
