1. 16. Chromium martensitic hot-work tool steels : damage, performance and microstructure

   Författare :Johnny Sjöström; Jens Bergström; Farhad Rezai-Aria; Karlstads universitet; []
   Nyckelord :Hot-work tool steel; thermal fatigue; microstructure; Materialteknik; Materials Engineering;

   Sammanfattning : Chromium martensitic hot-work tool steel (AISI H13) is commonly used as die material in hot forming techniques such as die casting, hot rolling, extrusion and hot forging. They are developed to endure the severe conditions by high mechanical properties attained by a complex microstructure. LÄS MER

   Sammanfattning : Friction stir welding (FSW) has undergone a rapid expansion in several industrial sectors such as in the aerospace, marine, railway and automotive sectors. Current industrial applications are mainly simple long straight welds, but there is a growth of interest in components with higher geometric complexity. LÄS MER

4. 18. Textured insert for improved heat extraction in combination with high-pressure cooling in turning of superalloys

   Författare :Nageswaran Tamil Alagan; Tomas Beno; Uta Klement; Anders Wretland; Högskolan Väst; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 718; High-pressure coolant; Heat dissipation; Textured insert; Tungsten carbide; Tool life; Tool wear; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

   Sammanfattning : Heat generated in a machining process is a common and critical obstacle faced in today's machining industries. The heat generated in the cutting zone has a direct negative influence on the tool life which, in turn contributes to increase the manufacturing costs. LÄS MER

5. 19. Development of Dual-broadband Rotational CARS for Combustion Diagnostics

   Författare :Joakim Bood; Förbränningsfysik; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; N2; O2; C2H2; Dimethyl Ether DME ; High pressure; Stray light filtering; multi-point CARS; CARS; Temperature; Engine knock; Physics; Fysik; Fysicumarkivet A:2000:Bood;

   Sammanfattning : The present thesis concerns development and application of dual-broadband rotational coherent anti-Stokes Raman spectroscopy (DB-RCARS) for temperature and species concentration measurements in combustion processes. Both fundamental development of the technique, including experimental as well as modelling results, and measurements in practical combustion devices were conducted. LÄS MER

7. 20. High Temperature Tribology of Aluminium : Effect of Lubrication and Surface Engineering on Friction and Material Transfer

   Författare :Justine Decrozant-Triquenaux; Jens Hardell; Manel Rodriguez Ripoll; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine Elements; Maskinelement;

   Sammanfattning : Lightweight design for automotive applications has been pursued for several decades and continues to increase. The main driving forces are new and increasingly stringent emission regulations as well as the increasing popularity of electric, or hybrid, vehicles where the increased weight of the batteries need to be compensated by light weight structures.
