  2. 11. Micro-scale studies of wear

    Author : Rickard Gåhlin; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Wear; micro-scale; methods; fundamental studies; AFM; micromechanical; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : The development of materials for tribological components is constantly striving to more sophisticated properties, specialised for specific applications. This progress requires and depends to a large extent on a parallel development of the theoretical knowledge of wear and on development of the experimental tools for investigating wear in the research lab as well as in the field.

  5. 13. Structural studies of InGaAsP/InP-based lasers : By Thomas Kallstenius

    Author : Thomas Kallstenius; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Materialvetenskap; Materials science; Teknisk materialvetenskap; materialvetenskap; Materials Science;

    Abstract : Reliable buried-heterostructure (BH) InGaAsP/InP-based laser diodes (LDs) is essentialto the operation of fiber optics communication systems. In this thesis, the structural,electrical and optical properties of such LDs have been studied. The aim has been toidentify materials-related mechanisms causing gradual emission degradation.

  7. 15. Relaxation and nanomechanical studies of the vickers residual stress field in glass

    Author : Kwadwo O. Kese; Bill Bergman; Sture Hogmak; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; soda-lime glass; vickers residual stress field; nanoindentation; stress rekaxatuib; cube corner indenter; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : The Vickers residual stress field (VRSF) in soda-lime glass results from the elastic-plastic contact event that takes place when a Vickers diamond pyramid is loaded onto the surface of the material in an indentation cycle. The importance of elastic-plastic indentation lies in the contact damage that it gives rise to in the surface of the glass. READ MORE
