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. Investigation of the Microstructure of Plastically Deformed Cemented Carbide

   Master-uppsats, KTH/Materialvetenskap

   Författare :Felicia Larsson; [2023]
   Nyckelord :;

   Sammanfattning : 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. 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.

   Kandidat-uppsats, Malmö universitet/Institutionen Idrottsvetenskap (IDV)

   Författare :Viktor Tingfors; André Sandgren; [2023]
   Nyckelord :Relative Age Effect; Icehockey; Physical maturity; WJC-18; WJC-20; WC.;

   Sammanfattning : Purpose: The purpose of this study is to investigate whether the Relative Age Effect iscrucial for winning the senior, U20, and U18 Men's Ice Hockey World Championships. Wealso aim to gain a better understanding of the significance of the Relative Age Effect for ateam's success. LÄS MER

7. 5. Världsmästerskapen i Sportswashing

   Kandidat-uppsats, Lunds universitet/Företagsekonomiska institutionen

   Författare :Emil Hörlin; Johan Otterhed Bolin; Deyar Reberius; [2023]
   Nyckelord :Country image; Sportswashing; Soft power; Qatar; Fotbolls-VM; Business and Economics;

   Sammanfattning : Forskningsfråga: Hur påverkas landet Qatars varumärke och internationella anseende av att arrangera fotbolls-VM 2022? Syfte: Syftet med denna uppsats är att undersöka hur sportswashing i form av ett internationellt idrottsevenemang påverkar ett lands varumärke. En fallstudie på Qatar och dess användande av fotbolls-VM 2022 har utförts för att öka och fördjupa förståelsen kring sportswashing. LÄS MER
