  2. 11. Metal release from powder particles in synthetic biological media

    Author : Klara Midander; Jinshan Pan; Mats Norell; KTH; []
    Keywords : 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;

    Abstract : Humans are exposed to metals and metal-containing materials daily, either conscious, e.g. using metal tools or objects, or unconscious, e.g. READ MORE

  4. 12. Numerical simulation of shape rolling

    Author : Stanislav Riljak; Stefan Jonsson; Peter Gudmundson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; shape rolling; wire-rod rolling; finite-element method; generalized plane-strain; dislocation density; material model; Other materials science; Övrig teknisk materialvetenskap;

    Abstract : In the first part of this thesis, the FE program MSC.Marc is applied for coupled thermomechanical simulations of wire-rod rolling. In order to predict material behaviour of an AISI 302 stainless steel at high strain rates generated during wire-rod rolling, a material model based on dislocation density is applied. READ MORE

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

    Author : Jan Sandberg; Inger Odnevall Wallinder; Dan Persason; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 14. Electronic structure and optical properties of PbY and SnY (Y=S, Se, and Te)

    Author : Nilton Souza Dantas; Clas Persson; Natalia Skorodumova; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Other materials science; Övrig teknisk materialvetenskap;

    Abstract : Lead chalcogenides and tin chalcogenides and their alloys are IV−VI family semiconductors with unique material properties compared with similar semiconductors. For instance, PbY (Y = S, Se, and Te) are narrow-gap semiconductors with anomalous negative pressure coefficient and positive temperature coefficient. READ MORE

  7. 15. Simulation of diffusional processes in alloys : techniques and applications

    Author : Henrik Strandlund; John Ågren; John Morral; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diffusion; Kirkendall effect; Phase transformations; Random walk; Solute drag; Interfacial mobility; Other materials science; Övrig teknisk materialvetenskap;

    Abstract : This thesis concerns computer simulation of diffusional processes in alloys. The main focus is on the development of simulation techniques for diffusion in single-phase domains, but also diffusion controlled phase-transformations and interfacial processes are discussed. READ MORE
