    Abstract : This thesis focuses on the effect of microstructural variation on the mechanical properties and deformation behavior of ductile iron. To research and determine these effects, two grades of ductile iron, (i) GJS-500-7 and (ii) high silicon GJS-500-14, were cast in a geometry containing several plates with different section thicknesses in order to produce microstructural variation.

  2. 2. Mechanical Properties of Semi-Solid Al Castings : Role of Stirring

    Author : Qing Zhang; Anders E.W. Jarfors; Stefan Jonsson; Jens Bergström; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rheometal™ process; aluminium alloys; stirring; segregation; porosity; oxides; ductility; fatigue performance;

    Abstract : Semi-solid metal (SSM) casting has been widely used in automotive industries to reduce the weight. In RheoMetalTM process which is one of the variations of SSM, the slurry fabrication can be finished within 30 second and can the slurry making process can be integrated into a high pressure die casting (HPDC) route without significant adjustments, making the process a promising alternative for industrial application.

  5. 5. Getting physical : tangibles in a distributed virtual environment

    Author : Mattias Bergström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design; Funktionella produkter; Functional Product Development;

    Abstract : The design of products is an increasingly complex task, where companies do not have and do not want the in-house competence to manage the development of entire products. Consequently, companies outsource parts of product development projects to other companies or join in partnerships. READ MORE
