6. 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.

7. 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

8. Evaluation of Refined Tribological Properties of Diamond Coated Cutting Tools Used in Machining of High-Strength Aluminum Alloys : Master thesis report regarding refined frictional & wear behavior of uncoated & CVD diamond coated WC-Co cemented carbide cutting tools used for machining of Al 7xxx alloys.
University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)Abstract : High strength aluminum alloys have for a long time been a popular material utilized in the automotive and aerospace sector due to coveted mechanical properties in terms of weight, strength, fatigue, and corrosion. However, tribological mechanisms such as tribo-film formation and material transfer during the metal cutting manufacturing process of aluminum impose significant reduction of machining and tool-life performance.

9. Performance and Wear Behaviour of Coated and Uncoated Cemented Carbide Tools during Milling of Titanium Alloys
University essay from Lunds universitet/Industriell ProduktionAbstract : Purpose – The purpose of this project is to study the performance of uncoated versus coated cemented carbide tools when performing milling operations in heat treated titanium alloys, with the goal of establishing a base line of knowledge and methodology linked to these difficult-to-machine materials relevant for the metal cutting industry. Design/methodology/approach – The work that is carried out in this project comprise both literature review, that is presented as the state of the art as the necessary theoretical background to understand what is done; and experiments, that were designed and executed at Seco Tools in Fagersta in order to achieve the primary goal, testing and comparing different scenarios where cutting parameters played a key role.

10. 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
