  1. 16. Stainless steels fabricated by laser melting : Scaled-down structural hierarchies and microstructural heterogeneities

    Författare :Kamran Saeidi; Zhijian Shen; Xiaoxu Huang; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Selective laser melting; Stainless steel; Structural hierarchies; Microstructure heterogeneity; Mechanical properties; Materials Chemistry; materialkemi;

    Sammanfattning : Additive manufacturing is revolutionizing the way of production and use of materials. The clear tendency for shifting from mass production to individual production of net-shape components has encouraged using selective laser melting (SLM) or electron beam melting (EBM). LÄS MER

  3. 17. On customization of orthopedic implants - from design and additive manufacturing to implementation

    Sammanfattning : Ti-6Al-4V manufactured by electron beam melting Keywords: Additive manufacturing, high-temperature tensile properties, low cycle fatigue, neutron diffraction, fatigue crack growth ISBN: 978-91-89325-27-2 (Printed) 978-91-89325-26-5 (Electronic) Ti-6Al-4V is the most widely used α+β titanium alloy in aerospace engine applications due to its high specific strength. Typically, the alloy is manufactured as castings or forgings and then machined to final geometry. LÄS MER

  7. 20. Microstructure Modelling of Additive Manufacturing of Alloy 718

    Författare :Chamara Kumara; Per Nylén; Johan Moverare; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase-Field Modelling; Laser metal powder directed energy deposition; Electron Beam Melting; Heat Treatment; Superalloy; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : In recent years, additive manufacturing (AM) of Alloy 718 has received increasing interest in the field of manufacturing engineering owing to its attractive features compared to those of conventional manufacturing methods. The ability to produce complicated geometries, low cost of retooling, and control of the microstructure are some of the advantages of the AM process over traditional manufacturing methods. LÄS MER
