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

    Författare :Kamran Saeidi; Zhijian Shen; Xiaoxu Huang; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; 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

  2. 2. Geometry Assurance of Laser Processed Metal Components

    Författare :Vaishak Ramesh Sagar; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; selective laser melting; Geometry assurance; geometric variation; selective laser heat treatment; robust design;

    Sammanfattning : The manufacturing industry largely contributes to the global economy. How-ever, with the growing complexity of customer demands, stringent environmental norms, and requirements for shorter product development lead times, the industry continues to seek alternatives to address these challenges.

    Sammanfattning : The thesis focuses on exploring the sub-grain structure in stainless steel 316L prepared by additive manufacturing (AM). Two powder-bed based AM methods are involved: selective laser melting (SLM) and electron beam melting (EBM). LÄS MER

  4. 4. Additive metallurgy - Thermal influences on structure and properties of stainless steel 316L

    Författare :Jon Olsén; Zhijian James Shen; Dongdong Gu; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Additive manufacturing; Selective laser melting; Electron beam melting; Hot isostatic pressing; Stainless steel; Microstructural heterogeneity; Materials Chemistry; materialkemi;

    Sammanfattning : Additive manufacturing (AM) as a manufacturing process has, in recent years, become widely accepted as capable of manufacturing parts that will be used in end products. In this thesis, stainless steel grade 316L parts are manufactured using two different powder bed fusion techniques, selective laser melting (SLM) and electron beam melting (EBM). LÄS MER

  5. 5. Some aspects on designing for metal Powder Bed Fusion

    Författare :Sebastian Hällgren; Lars Pejryd; Jens Ekengren; Robert Pederson; Örebro universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Additive Manufacturing; AM; DfAM; lattice; Powder Bed Fusion; Topology optimization; Selective Laser Melting; Electron Beam Melting; Design for manufacturability;

    Sammanfattning : Additive Manufacturing (AM) using the Powder Bed Fusion (PBF) is a relatively new manufacturing method that is capable of creating shapes that was previously practically impossible to manufacture. Many think it will revolutionize how manufacturing will be done in the future. LÄS MER
