  1. 1. Fatigue Assessment of Cast Components : Influence of Cast Defects

    Författare :Anders Björkblad; Jack Samuelsson; Gary Marquis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cast nodular iron; fatigue; design rules; fracture mechanics; Vehicle engineering; Farkostteknik;

    Sammanfattning :  This thesis is on the fatigue assessment of cast components with special attention to defects. The primary material in view is nodular cast iron, but also cast steel is considered. However, the fatigue behaviour is in principle valid for general use on other cast metals. LÄS MER

  3. 2. On the Nucleation and Inoculation of Metals

    Författare :Lena Magnusson; Hasse Fredriksson; Peter Schumacher; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solidification; nucleation; inoculation; undercooling; interface energy; refractory metals; latent heat; inclusions; nodular cast iron; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Latent heat during recalesence and nucleation and post-recalesence temperature was analysed for refractory metals. An effect on latent heat was found by alloying the pure elements with other refractories. Latent heat was found to be 15-65% of tabulated values. Interface energy was evaluated from undercooling experiments. LÄS MER

  5. 4. Al-Si Cast Alloys - Microstructure and Mechanical Properties at Ambient and Elevated Temperatures

    Författare :Mohammadreza Zamani; Salem Seifeddine; Anders Jarfors; Franco Bonollo; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminium cast alloys; eutectic modification; microstructural scale effect; transition metals; room and elevated temperatures tensile properties; physically-based constitutive model.;

    Sammanfattning : Swedish industry is a global leader in development and manufacture of automotive and aviation components where the usage of aluminium products is remarkable. In addition to manufacturing aluminium components, casting enables low-cost and low-emission production of complex geometry components with a range of sizes. LÄS MER

  7. 5. Microstructural Evolution In As-cast Alloys during Plastic Deformation

    Författare :Mitra Basirat; Pär Jönsson; Hasse Fredriksson; Jacques Lacaze; KTH; []
    Nyckelord :plastic deformation; compression test; recrystallization; deformation band; As-cast; microsegregation; carbide dissolution; disordered structure; order disorder transformation; twining; steel; β brass; copper; SRA - E-Science SeRC ; SRA - E-vetenskap SeRC ;

    Sammanfattning : The effect of deformation on microstructural changes in metals and alloys is the subject of considerable practical interest. The ultimate goal is to control, improve and optimize the microstructure and texture of the finished products produced by metal forming operations. LÄS MER
