    Författare :Munir Al-Saadi; Pär Jönsson; Christopher Hulme-Smith; Göran Engberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alloy 825; Cast and wrought structures; Hot compression test; Microstructural evaluation; Modelling; Yield strength; Strengthening mechanisms; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : Alloy 825 material was studied using a Gleeble-3800 thermosimulatorby performing single-hot compression experiments.Optical microscopy and electron backscatter diffraction wereutilized to characterize the microstructure. Dynamicrecrystallization is not considerable in the as-cast alloy anddislocation recovery is deemed to be dominant. LÄS MER

  3. 2. Investigations on the Formation of Defect Bands in Semi-Solid High Pressure Die Cast Aluminium-Silicon Alloys

    Sammanfattning : High-pressure die casting of semi-solid aluminium-silicon alloys is used in the automotive industry to manufacture components, like housings, brackets, and bars. It is commonly known that during high-pressure die casting, defect bands may be created that follow the contour of the component surface. These bands consist mainly of a eutectic phase. LÄS MER
