  1. 6. Rheocasting of aluminium alloys : Process and components characteristics

    Författare :Mostafa Payandeh; Anders E. W. Jarfors; Magnus Wessén; Helen Atkinson; Jönköping University; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rheocasting; aluminium alloy; RheoMetal TM process; microstructural characteristics; component properties and performance; robust design process;

    Sammanfattning : Semi-Solid Metal (SSM) casting is a promising technology offering an opportunity to manufacture net-shape, complex geometry metal components in a single operation. However, the absence of foundry guidelines and limited design data for SSM casting makes it challenging to predict the performance of both process and components. LÄS MER

  5. 9. Processing Aspects for Improving Mechanical Properties in Aluminium Castings

    Författare :Jonas Bäckman; Linköpings universitet; []
    Nyckelord :Aluminium; microstructure; mechanical properties; gradient solidification; mould filling; filter; filter parameter; casting simulation; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The relation between the process and mechanical properties in aluminium alloys for castings has been examined. The relation was hard to define since the spread in data was severe due to defects created in the casting process. To avoid such defects a gradient solidification equipment was built. LÄS MER
