  1. 21. Modeling the microstructural evolution during hot working of C-Mn and Nb microalloyed steels using a physically based model

    Författare :Linda Lissel; Stefan Jonsson; Bertil Ahlblom; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; austenite; modeling; hot deformation; microstructure evolution; static recrystallization; dynamic recrystallization; metadynamic recrystallization; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : Recrystallization kinetics, during and after hot deformation, has been investigated for decades. From these investigations several equations have been derived for describing it. The equations are often empirical or semi-empirical, i.e. LÄS MER

  3. 22. Metal release from powder particles in synthetic biological media

    Författare :Klara Midander; Jinshan Pan; Mats Norell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; metal release; stainless steel; Cu; powder particles; synthetic body fluids; test method; in vitro tests; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : Humans are exposed to metals and metal-containing materials daily, either conscious, e.g. using metal tools or objects, or unconscious, e.g. LÄS MER

  4. 23. Densities and viscosities of slags : modeling and experimental investigations

    Författare :Mikael Persson; Seshadri Seetharaman; Rob Brooks; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; density; nolar volume; thermodynamics; enthalpies; model; slags; oxide melts; viscosity; mould flux; continuous casting; Metallurgical process engineering; Metallurgisk processteknik;

    Sammanfattning : The present dissertation describes part of the efforts directed towards the development of computational tools to support process modeling. This work is also a further development of the Thermoslag software developed in the Division of Materials Process Science, KTH. LÄS MER

  5. 24. Corrosion-induced release of zinc and copper in marine environments

    Författare :Jan Sandberg; Inger Odnevall Wallinder; Dan Persason; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; copper; zinc; marine environment; runoff rate; atmospheric corrosion; chloride deposition; anti-fouling paints; chemical speciation; bioavailability; cupric ions; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : This licentiate study was initiated by copper, zinc and galvanized steel producers in Europe, who felt a need to assess runoff rates of copper and zinc from the pure metals and commercial products at marine exposure conditions. Their motive was the increasing concern in various European countries and the on-going risk assessments of copper and zinc within the European commission. LÄS MER

  7. 25. Modeling Phase Transformations and Volume Changes during Cooling of Case Hardening Steels

    Författare :Matilda Tehler; Stefan Jonsson; Åsa Gustafson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase transformation; volume changes; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : Case hardening distortions are a major problem for gear manufacturers. The aim of the current work is to create a simulation model, able to predict how and when case hardening distortions arise. The results presented in this thesis form a basis for such a model. Two case hardening steels, with base carbon contents of 0. LÄS MER
