  2. 11. High Performance Aluminium Alloys for Laser Powder Bed Fusion: Alloy Design and Development

    Author : Bharat Mehta; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; Precipitation Kinetics; Integrated Computational Materials Engineering; Laser Based Powder Bed Fusion; Heat Treatment; Aluminium Alloys;

    Abstract : Additive Manufacturing (AM), particularly Laser Based Powder Bed Fusion (LB-PBF) has proven to be a notable technology to produce novel microstructures and expand the ceiling of product design. However, the development of novel alloys in metal LB-PBF has not followed the same pace as development of product design. READ MORE

  4. 12. Casting and anodising of Al alloys- Alloy design, manufacturing process and material properties

    Author : Baiwei Zhu; Caterina Zanella; Rajan Ambat; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cast aluminium; Semi-solid casting; Anodising; Gjutning av aluminium; semi-solid gjutning; anodisering; komponent; gjutlegering; kisel; järn;

    Abstract : Casting and semi-solid metal (SSM) casting are widely used to manufacture near-net-shape components of Al-Si alloys in the automotive and electronic industries. In such applications, casting components need to meet the combined requirements of good mechanical properties and corrosion and wear resistance. READ MORE

  5. 13. High performing cast aluminium-silicon alloys

    Author : Martin Riestra; Salem Seifeddine; Ehsan Ghassemali; Jessica Elfsberg; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aluminium cast alloys; melt quality; eutectic modification; grain refinement; microstructure; tensile properties;

    Abstract : The need to produce lighter components due to environmental aspects and the development of electrical vehicles represents an opportunity for cast aluminium-silicon alloys. With high specific strength, good castability, high corrosion resistance and recyclability, these alloys offer an attractive combination of properties as an alternative to steel, cast iron and titanium-based components in certain applications.

  6. 14. Simulation of Phase Transformations and coarsening : Computational tools for alloy development

    Author : Johan Jeppsson; John Ågren; Gerhard Inden; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; Teknisk materialvetenskap;

    Abstract : The final properties of an alloy are highly interlaced with its microstructure. It is therefore essential to control the evolution of the microstructure of the material during the fabrication process. Nowadays, materials design involves an increasing part of computational design to complement the traditional experimental trial and error approach. READ MORE

  7. 15. Development and evaluation of hybrid joining for metals to polymers using friction stir welding

    Author : Wallop Ratanathavorn; Arne Melander; Stefan Hallström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aluminium alloy; thermoplastic; friction stir welding; dissimilar joining; Production Engineering; Industriell produktion;

    Abstract : Combinations of different materials are increasingly used in the modern engineering structures. The driving forces of this trend are rising fuel costs, global warming, customer demands and strict emission standards. READ MORE
