   Nyckelord :HUMANIORA; HUMANITIES; SLA; EAL; CALL; DDL; Educational Linguistics; English; Upper-secondary; Education Technology; Diganostics; Tool; Engelska med didaktisk inriktning; English Education; Lingvistik; Linguistics;

   Sammanfattning : This dissertation explores the design and application of a digital tool as a supporting aid for teachers of English in Swedish upper-secondary classrooms. The scope of this dissertation is the design, development and evaluation of a focus-on-form diagnostics tool in the Swedish upper-secondary English subject context. LÄS MER

3. 7. Machinability variations in Alloy 718 —With focus on machining of turbine components

   Författare :Pajazit Avdovic; Industriell Produktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polar diagram; flank wear; ceramic tool; variation in material; tool wear; tool life; machinability; Inconel; Alloy 718; Machining; notch wear;

   Sammanfattning : In gas turbine engine, nickel base alloy, such as Alloy 718, accounts for almost half of the total material requirement. Nickel-base superalloys are used for gas turbine components mainly because of their outstanding strength and resistance to oxidation at high temperatures (> 550°C). LÄS MER

4. 8. On Polishability of Tool Steels

   Författare :Sabina Rebeggiani; Bengt-Göran Rosén; Liam Blunt; Högskolan i Halmstad; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tool steels; polishability; surface characterisation; surface texture parameters; high gloss polishing; injection moulding;

   Sammanfattning : One of the world’s fastest growing industries is the plastic industry. Today’s ever increasing demands of high quality products, shorter lead times and reduced costs push development and research forwards. LÄS MER

5. 9. Tool Life and Cutting Data Modelling in Metal Cutting : Testing, Modelling and Cost Performance

   Författare :Daniel Johansson; Industriell Produktion; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metal cutting; tool life; tool wear; cutting data; process cost; Colding model; part cost;

   Sammanfattning : One of the most important production processes in industry is metal cutting. If a product is not a machined metal part, it is likely that the mould, die and tools used to produce the product or parts of the product are machined. LÄS MER

7. 10. Multicomponent diffusional reactions in tool steels : Experiment and Theory

   Författare :Greta Lindwall; Malin Selleby; Karin Frisk; John Ågren; Carelyn Campbell; KTH; []
   Nyckelord :hot-work tool steel; precipitation hardening; DICTRA; coarsening; mobilities; CALPHAD; cobalt; PM tool stees; nitrogen; compound materials;

   Sammanfattning : Many phenomena determining the microstructure of a tool steel and consequently the properties of the material, are governed by multicomponent diffusion. The diffusion driven reactions that take place during, for example, tempering of a hot-work tool steel or when the microstructure develops during hot isostatic pressing of cold-work tool steel, are dependent on the types and amounts of alloying elements.
