  5. 23. On the microstructure and mechanical properties of Mg-Al alloys

    Author : Haiping Cao; Linköpings universitet; []
    Keywords : Mg-AI; microstructure; mechanical properties; divorced degree; modeling; mould constraint; segregation band; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The microstructural features and the mechanical properties of binary Mg-Al alloys have been investigated by using a gradient solidification technique. Homogeneous and nearly defect-free samples were produced under well controlled cooling conditions, through which the microstructural characteristics as well as the relationships between microstructure and mechanical properties in Mg-AI alloys were precisely defined.

  6. 24. Electron beam-powder bed fusion of Alloy 718 : Effect of process parameters on microstructure evolution

    Author : Paria Karimi Neghlani; Joel Andersson; Joakim Ålgårdh; Iain Todd; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive manufacturing; Electron beam-powder bed fusion; Microstructure evolution; Microstructure tailoring; Process understanding; Alloy 718; Production Technology; Produktionsteknik;

    Abstract : Additive manufacturing (AM) is the technology of building 3D parts through layer-by-layer addition of material. Of the different types of AM techniques, electron beam-powder bed fusion (EB-PBF) has been used in this study. EB-PBF can build parts by melting metallic powders using an electron beam as the energy source. READ MORE

  7. 25. Laser powder bed fusion processing and heat treatment of Ni-base superalloys: microstructure and properties

    Author : Abdul Shaafi Shaikh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; microstructure.; Additive manufacturing; heat treatment; Inconel 939; Haynes 282; superalloys; powder bed fusion – laser beam;

    Abstract : Nickel-base superalloys are indispensable materials for the energy and aerospace industries. The additive manufacturing (AM) of these materials by powder bed fusion – laser beam (PBF-LB) presents a valuable opportunity to improve component performance and ease manufacturing and supply chain complexity in these industries.
