1. The Application of Multivariate Statistical Process Control during Industrial Hot Isostatic Pressing Sintering Processes : A Case study at Seco Tools AB
University essay from Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälleAbstract : This Master's thesis focuses on improving the understanding and monitoring of the Hot Isostatic Pressing (HIP) sintering process used by Seco Tools AB to manufacture cemented carbides for cutting tools. While essential for producing cutting tools with superior hardness and toughness the HIP sintering process introduces a complex relationship between the selected process parameters and the achieved materials properties.

2. Investigation of the Microstructure of Plastically Deformed Cemented Carbide
University essay from KTH/MaterialvetenskapAbstract : During machining operation, cemented carbide tools are exposed to high loads and temperatures, which eventually leads to plastic deformation of the tool material. The aim of this work was to investigate if the microstructures of creep deformed micro grain cemented carbides can be linked to alloying elements and mechanical properties. READ MORE

3. The Effect of Alternative Tungsten Carbide Grain Size Distribution on Microstructure and Mechanical Properties in Cemented Carbides
University essay from KTH/MaterialvetenskapAbstract : In the constant pursuit of better-performing cemented carbides, recent studies suggest that a combination of better hardness and toughness can be obtained by changing its WC grain size distribution. As the area is still rather unexplored, this thesis aims to broaden the knowledge and answer whether mechanical properties can be changed by changing the WC grain size distribution, in the context of mining drill bit inserts.

4. Evaluation of a novel method to investigate diffusion between copper-zinc alloys and cemented carbides
University essay from Uppsala universitet/Tillämpad materialvetenskapAbstract : When slow wear mechanisms are studied it is important to examine slower processes, such as diffusion. Such processes can have a significant impact over time and can cause other phases to form, which can have a large effect on the wear. READ MORE

5. Effect of post-treatment of cemented carbide : Microstructural investigation and evaluation of mechanical properties of cemented carbide inserts for rock tool applications
University essay from Karlstads universitet/Avdelningen för maskin- och materialteknikAbstract : Cemented carbides are used in rock tool applications by reason of their beneficial mechanical properties, i.e. a combination of high toughness, wear resistance and hardness. The cemented carbides commonly receive their hardness from tungsten carbides (WC) whereas cobalt (Co) is the dominating binder material. READ MORE
