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

    Författare :Anders Lagerstedt; Hasse Fredriksson; Alec Mitchell Mitchell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; material science; mechanical engineering; metallurgy; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Sammanfattning : 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.

  3. 2. On the analysis of cast structure and its changes during hot working of forging ingots

    Författare :Jan Sarnet; Hasse Fredriksson; Alec Mitchell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Teknisk materialvetenskap;

    Sammanfattning : Forging ingots are hot worked to consolidate structural imperfections and refine the microstructure. Possible imperfections are segregations, porosities, cracks, and inclusions. In this thesis, techniques and methods for the characterisation of behaviour and properties of ingots and forgings. LÄS MER
