  2. 2. Processing Aspects for Improving Mechanical Properties in Aluminium Castings

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

    Abstract : 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. READ MORE

  3. 3. Characteristics of cast aluminium-silicon alloys : microstructures and mechanical properties

    Author : Salem Seifeddine; Birger Karlsson; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Aluminium; Mocrostructure; Porosity; Tensile properties; Modelling; Chemical process and manufacturing engineering; Kemisk process- och produktionsteknik; Aluminium; microstructure; porosity; tensile properties; modelling.; Materials science; Teknisk materialvetenskap;

    Abstract : Applications of aluminium alloys are spreading in many industrial fields due to the excellent combination of castability, mechanical performance and lightness assured by such material. This project aims to establish a methodology in bringing the foundry process closer to the casting designer, and thereby leading to a more reliable and more optimised design. READ MORE

    Abstract : 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. READ MORE
