1. 1. Investigation of the Microstructure of Plastically Deformed Cemented Carbide

   University essay from KTH/Materialvetenskap

   Author : Felicia Larsson; [2023]
   Keywords : ;

   Abstract : 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. 2. Investigations of Tool Wear Mechanisms in the Turning of Conventional, Calcium Treated and Ultraclean Steels

   University essay from KTH/Materialvetenskap

   Author : Milou Göransson; [2023]
   Keywords : Clean steel; Ultraclean steel; Longitudinal turning; Cemented carbide cutting tool; Chemical vapor deposition coating; Machinability; Tool wear; Non-metallic inclusions; Rent stål; Ultrarent stål; Längdsvarvning; Hårdmetall skärverktyg; Kemisk ångdeponering beläggning; Bearbetningsbarhet; Verktygsslitage; Icke-metalliska inneslutningar.;

   Abstract : Application of clean and ultraclean steels have shown to provide favourable mechanical properties for bearings and transmission components, specifically regarding fatigue performance, compared to conventional steel grades. Clean steels are characterized by containing a very low level of non-metallic inclusions. READ MORE

4. 3. Study of Porosity in Uncoated Cemented Carbide Tools During Titanium Alloy Machining.

   University essay from Lunds universitet/Industriell Produktion

   Author : Cornelis Botermans; [2023]
   Keywords : Technology and Engineering;

   Abstract : During high speed machining of titanium alloys both the tool and workpiece material diffuse into one another affecting the surface integrity of the cutting tool edge and leading to fracture. One proposed mechanism by which the tool integrity is compromised results from the possible formation of porosity in to subsurface of the tool substrate close to the tool cutting edge. READ MORE

5. 4. Analysis of granulated carbide powder and how it affects pressing

   University essay from KTH/Materialvetenskap

   Author : Maeva Anfossi; Emma Hjortzberg-Nordlund; Linnéa Lundemo Mattsson; [2023]
   Keywords : Cemented Carbide Tools; Pressing Agent; Flowability; Tap Density; Angle Of Repose; Hall Flow Time; Particle Size Distribution; Powder Rheometer; Compatibility; Hårdmetallverktyg; Pressmedel; Flytbarhet; Tapp Densitet; Rasvinkel; Hall Flödestid; Partikelstorleksfördelning; Pulverrheometri; Kompatibilitet;

   Abstract : During the pressing of powder mixtures to make cemented carbide tools, the degree to which the powder spreads to fill the die and to which it compacts is uncertain. This leads to inconsistent dimensions and densities in the finished product. READ MORE

6. 5. The Effect of Alternative Tungsten Carbide Grain Size Distribution on Microstructure and Mechanical Properties in Cemented Carbides

   University essay from KTH/Materialvetenskap

   Author : Filip Ivarsson; [2022]
   Keywords : Cemented Carbides; WC Grain Size Distribution; Mechanical Properties; Microstructure Analysis; Hårdmetall; WC Kornstorleksfördelning; Mekaniska Egenskaper; Mikrostruktur Analys;

   Abstract : 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.
