  1. 1. Development of a Method to Measure Residual Stresses in Cast Components with Complex Geometries

    Master-uppsats, KTH/Materialvetenskap

    Författare :Yang Yang; [2020]
    Nyckelord :Residual Stresses; Cast Iron; Engine Components; XRD; Ultrasonic; Cutting;

    Sammanfattning : Cast iron, taking the advantages of the advanced castability forming components of complex geometries and favorable mechanical properties, is employed in engine components in truck industries. Compacted graphite iron (CGI) integrates both merits of lamellar graphite iron (LGI) and spheroidal graphite iron (SGI) such as good machinability and high thermal conductivity from LGI, high ultimate tensile strength (UTS), good fatigue resistance, high elastic modulus, and high ductility from SGI, thus is now becoming a competitive alternative of traditional LGI in cylinder blocks and heads.

  3. 2. Mätning av restspänning i kromoxid : En jämförelse mellan krom och kopparstrålning i röntgendiffraktion

    Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Viktor Sjöström; [2019]
    Nyckelord :;

    Sammanfattning : A doctor blade among other applications is used in the paper industry, were its main purpose is to separate paper sheet from a drying cylinder. During spraying, the blade is exposed to wear by its continuous contact with the moving cylinder. The blade has been sprayed with a chromium oxide coating to withstand wear. LÄS MER

  4. 3. Metod för mätning av restspänningar i PVD-beläggningar på tunna substrat

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Philip Eriksson; Emily Hall; Felix Jacobson; Ebba Saikoff; Johanna Söderberg; Pontus Theill; Erika Åkerfeldt; [2016]
    Nyckelord :Residual stress measurement; PVD coatings; thin substrates; foil; Mätning av restspänningar; PVD skikt; tunna substrat; folie;

    Sammanfattning : The aim of this project was to, based on a given idea, develop and evaluate a method for measuring residual stress in thin PVD coatings. AlCrN was deposited, by PVD, on thin circular samples of stainless steel foil and the radius of the emerged curvature was measured using an optical profilometer. LÄS MER
