  1. 1. Tailoring structure and morphology during additive manufacturing of metallic components

    Författare :Jithin James Marattukalam; Björgvin Hjörvarsson; Ulf Jansson; Martin Sahlberg; Lars Nyborg; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Selective laser melting; process parameters; scanning methodologies; AMLOYZR01; bulk metallic glass; 316L SS; grain orientation;

    Sammanfattning : The work described in this thesis explores the use of laser process parameters to functionalize the material properties by the control of microstructure and optimization of morphology in components by selective laser melting. The microstructure in amorphous and crystalline metallic alloy systems is influenced by changing the laser power density and scanning strategies respectively. LÄS MER

    Sammanfattning : Additive manufacturing (AM), also known as 3D printing, is a general concept of building a three-dimensional object layer-by-layer. AM breaks through the manufacturing limitations in conventionally subtractive manufacturing, leading to a great design freedom of components with complex geometries. LÄS MER
