  1. 16. Characteristics of cast aluminium-silicon alloys : microstructures and mechanical properties

    Detta är en avhandling från Institutionen för konstruktions- och produktionsteknik

    Författare :Salem Seifeddine; Högskolan i Jönköping.; Högskolan i Jönköping.; Linköpings universitet.; Linköpings universitet.; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; Aluminium; microstructure; porosity; tensile properties; modelling.; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik; Aluminium; Mocrostructure; Porosity; Tensile properties; Modelling;

    Sammanfattning : Applications of aluminium alloys are spreading in many industrial fields due to the excellent combination of castability, mechanical performance and lightness assured by such material. This project aims to establish a methodology in bringing the foundry process closer to the casting designer, and thereby leading to a more reliable and more optimised design. LÄS MER

  2. 17. Multiscale modelling of total pressure effects on complete methane oxidation over Pd/Al2O3

    Detta är en avhandling från ; Chalmers tekniska högskola; Gothenburg

    Författare :Carl-Robert Florén; [2018]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; palladium oxide; mass and heat transport; multiscale modelling; reactor modelling; methane oxidation; first-principles calculations;

    Sammanfattning : The models used in heterogeneous catalysis are becoming more advanced and the literature shows an increased interest in incorporating the atomistic scale into microkinetics. Coupling kinetics based on first-principles calculations to macroscopic effects can pave the way towards more comprehensive modelling methods and to tailored catalyst designs. LÄS MER

  3. 18. Management of technology in the process industries:  Matching market and machine

    Detta är en avhandling från KTH Royal Institute of Technology

    Författare :Peter Samuelsson; KTH.; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process industries; manufacturing; innovation; configuration; strategizing; capability; configuration modelling; process industries; production system; physical modelling; AOD; converter geometry; injection; mixing times; electric arc furnace; EAF; post-combustion; high-impedance; network disturbances; operational results; Metallurgical process science; Metallurgisk processvetenskap;

    Sammanfattning : The process industries span multiple industrial sectors and constitute a substantial part of the entire manufacturing industry. Since companies belonging to this family of industries are often very asset intensive, their ability to respond to changes is often limited in the short term. LÄS MER
