    Författare :Tony Carlson; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science - Functional materials; Materials science - Other material science; Teknisk materialvetenskap - Funktionella material; Teknisk materialvetenskap - Övrig teknisk materialvetenskap; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Sammanfattning : The use of lightweight materials in structural applications is ever increasing. Today, lightweight engineering materials are needed to realise greener, safer and more competitive products. LÄS MER

  3. 3. Slag inclusion formation during solidification of steel alloys and in cast iron

    Författare :Sofia Adolfi; Hasse Fredriksson; Karin Hansson; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solidification; segregation; precipitation; inclusions; inoculation; EMPA; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : This thesis explores the formation of segregation and inclusions during solidification of steel and cast iron. A better understanding of the formation mechanism should result in decreasing fraction of defects during solidification of ingot and strand material. LÄS MER

  4. 4. Studies of transport in oxides on Zr-based materials

    Författare :Clara Anghel; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Zirconium; hydrogen; oxygen diffusion; second-phase particle; oxidation; dissociation; hydration; carbon monoxide; adsorption; porosity; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : Zr-based materials have found their main application in the nuclear field having high corrosion resistance and low neutron absorption cross-section. The oxide layer that is formed on the surface of these alloys is meant to be the barrier between the metal and the corrosive environment. LÄS MER

  5. 5. Point defect interactions and structural stability of compounds

    Författare :Vitaly Baykov; Börje Johansson; Peter Mohn; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; first principles; ab initio; density functional theory; point defects interactions; diluted magnetic semiconductors; structural stability; zirconium alloys; Other materials science; Övrig teknisk materialvetenskap;

    Sammanfattning : Theoretical studies of point defect interactions and structural stability of compounds have been performed using density functional theory. The defect-related properties, such as activation energy of diffusion, electronic and magnetic structure of selected materials have been studied. LÄS MER
