  1. 11. Metal Powder Benchmarking

    Master-uppsats, KTH/Materialvetenskap

    Författare :Ananthakrishna Sajithkumar; [2021]
    Nyckelord :Selective laser melting; powder characterisation; flow behaviour; Selektiv lasersmältning; karakterisering av pulver; flödesbeteende;

    Sammanfattning : Metal  additive  manufacturing  technologies  are  widely  employed  in  the aerospace, automotive  and  medical  industries. Selective  laser  melting  is  a type  of  metal additive manufacturing process in which powders are consolidated layer by layer in a predefined pattern with the help of a laser beam to create a component.

  3. 12. Linkage of Macro- and Micro-scale Modelling Tools for Additive Manufacturing

    Master-uppsats, KTH/Materialvetenskap

    Författare :Julia Sjöström; [2020]
    Nyckelord :Maraging steel; selective laser melting; temperature evolution; macro-scale modelling; segregation; ICME.;

    Sammanfattning : Additive manufacturing methods for steel are competing against commercial production in an increasing pace. The geometry freedom together with the high strength and toughness due to extreme cooling rates make this method viable to use for high-performance components. The desirable material properties originate from the ultrafine grain structures. LÄS MER
