    Författare :Jenny Wikström; Pär Jönsson; Lauri Holappa; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mathematical modeling; inclusion separation; tundish; ladle; slag; steel-slag interface; CSLM experiments; agglomeration; physical properties; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Sammanfattning : The aim of this thesis work is to increase the knowledge of inclusion behavior at the steel-slag interface by mathematical modeling and in-situ Confocal Scanning Laser Microscope experiments. Mathematical models based on the equation of motion predicting liquid and solid inclusion behavior was first investigated. LÄS MER

  3. 7. Corrosion-included metal runoff from external constructions and its environmental interaction : a combined field and laboratory investigation of Zn, Cu, Cr and Ni for risk assessment

    Författare :Sofia Bertling; Inger Odnevall Wallinder; Herbert E. Allen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Atmospheric corrosion; metal runoff; metal dispersion; soil; limestone; retention; Miljöteknik; Environmental engineering; Miljöteknik;

    Sammanfattning : The 1990s has seen an increased awareness of possible environmental effects of corrosion-induced metal release from outdoor constructions. Considerable efforts have been initiated to perform critical assessments of possible risks of selected metals. Gaps of knowledge have been identified and research investigations started. LÄS MER

  7. 10. On the effect of nitrogen, hydrogen and cooling rate on the solidification and pore formation in Fe-base and Al-base alloys

    Författare :Advenit Makaya; Hasse Fredriksson; Zhongyun Fan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Porous metals; Metal foams; Gas solubility; Fe-base alloys; Al-base alloys; M7C3 carbides; Al3Ti; Al3Fe; Rapid solidification; Metastable phases; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : Experiments on the production of porous metallic materials were performed on Fe-base and Al-base alloys. The method involves dissolution of gases in the liquid state and solidification at various cooling rates. The alloy compositions were selected to induce solidification of primary particles intended to control the pore distribution. LÄS MER
