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

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

    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

  4. 2. Semi-Solid Casting of Aluminium and Magnesium Alloys: Slurry Production and Rheocasting using the Rapid Slurry Forming Technology

    Author : Olof Granath; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Slurry; RheoMetal; Process parameter; Aluminium alloys; Semi-solid; Rheocasting; Rapid Slurry Forming; Magnesium alloys; Reheating;

    Abstract : Semi-solid casting was developed in the early 1970’s and involves the use of a partially solidified metal slurry. This method of casting has become a popular alternative for production of automobile components. READ MORE
