1. 1. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Ahsan Ali; [2023]
   Nyckelord :High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

   Sammanfattning : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

3. 2. Jämförelse av torr bearbetning och minimalsmörjningseffekter på fräsning av austenitiskt rostfritt stål

   M1-uppsats, Högskolan i Gävle/Maskinteknik

   Författare :Adam Norell; Darav Hajo; [2023]
   Nyckelord :MQL; milling; stainless steel; tool wear; MQL; fräsning; rostfritt stål; verktygsförslitning;

   Sammanfattning : Fräsning och annan intermittent skärande bearbetning ger upphov till termisk utmattning av skärverktyg. Problemet med termiska sprickor blir större vid bearbetning av värmehållfasta material som austenitiskt rostfritt stål eftersom värmeväxlingarna i skärverktyget blir mer extrema. LÄS MER

4. 3. Microstructure and Mechanical Investigation ofCarbides Particles Reinforced High AusteniticManganese Steel

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Abderrahim Ait ouakrim; [2023]
   Nyckelord :Metal Matrix Composites MMCs ; Manganese steel; Carbides particles; Wear resistance;

   Sammanfattning : The objective of this study was to produce a metal matrix composite (MMC). This compositematerial proves highly suitable for scenarios involving abrasive wear, owing to the exceptionalhardness of carbide particles, in conjunction with the remarkable ductility and capacity for workhardening found in Hadfield steel.

   Uppsats för yrkesexamina på grundnivå, Lunds universitet/Industriell Produktion

   Författare :Christian Jaunviksna; [2023]
   Nyckelord :Metal cutting Machinability Grey cast iron Tool wear Cutting data Hardness Microstructure Segmentation; Technology and Engineering;

   Sammanfattning : Grey cast iron is one of the most used materials in the automotive industry. The material has a range of properties that makes it suitable for machining applications, but manufacturers still experience machinability problems. LÄS MER

7. 5. Investigations of Tool Wear Mechanisms in the Turning of Conventional, Calcium Treated and Ultraclean Steels

   Master-uppsats, KTH/Materialvetenskap

   Författare :Milou Göransson; [2023]
   Nyckelord :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.;

   Sammanfattning : 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. LÄS MER
