  2. 2. Surface Engineering in Sheet Metal Forming

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Per Carlsson; Uppsala universitet.; Högskolan Dalarna.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap; materialvetenskap; Materials Science; Materials science; Friction; wear; metal coated steel sheet; dry lubricants; galling; PVD coatings; Materialvetenskap;

    Abstract : In recent years, surface engineering techniques have been developed in order to improve the tribological performance in many industrial applications. In sheet metal forming processes, the usage of liquid lubricants can be decreased by using self lubricated tribo surfaces which will result in more environmentally friendly workshops. READ MORE

  3. 3. Interfacial Phenomena in Two-Phase systems: Emulsions and slag Foaming

    University dissertation from Stockholm : Materialvetenskap

    Author : Abha Kapilashrami; KTH.; [2004]

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

    University dissertation from Materialvetenskap

    Author : Kwadwo O. Kese; KTH.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; soda-lime glass; vickers residual stress field; nanoindentation; stress rekaxatuib; cube corner indenter; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP 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

  5. 5. On the shrinkage of metals and its effect in solidification processing

    University dissertation from Stockholm : Materialvetenskap

    Author : Anders Lagerstedt; KTH.; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; material science; mechanical engineering; metallurgy; Materialvetenskap; TECHNOLOGY Materials science; TEKNIKVETENSKAP Teknisk materialvetenskap;

    Abstract : The shrinkage during solidification of aluminium and iron based alloys has been studied experimentally and theoretically. The determined shrinkage behaviour has been used in theoretical evaluation of shrinkage related phenomena during solidification.Air gap formation was experimentally studied in cylindrical moulds.
