  1. 1. Characterisation of additively manufactured Inconel 718 alloy by using electrolytic extraction

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Leyla Koort; Viktoria Sutorius Trollbäck; [2021]
    Nyckelord :;

    Sammanfattning : The formation of non-metallic inclusions (NMIs) are common in all steel grades and it is not possible  as  of  today  to  be able  to  remove  all  of them.  The  inclusions  are  categorised  into endogenous (oxides, nitrides, sulfides, carbides, and phosphides), and exogenous (entrapment of  nonmetals:  slag, mold).

  3. 2. 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.

  4. 3. Evaluating spreadability of metallic powders for powder bed fusion processes

    Master-uppsats, KTH/Materialvetenskap

    Författare :Vignesh Hari; [2020]
    Nyckelord :Additive manufacturing; spreadability; flowability; Additiv tillverkning; spridbarhet; flytbarhet; mätetal;

    Sammanfattning : Additive  manufacturing  technologies  are  widely  used  in  aerospace,  space,  and  turbine industries. Parts can be manufactured directly by selectively adding materials layer-by-layer. A key aspect that is critical to the quality of the final component being manufactured is the powder characteristics. LÄS MER

  5. 4. Investigation and Evaluation of Metal Powder Characterization Techniques : Currently available at the KTH Department of Material Science and Engineering

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Leo Hultén; Philip Jansson; [2018]
    Nyckelord :Powder Metallurgy; Metal Powder Characterisation; Evaluation; Investigation; Metal Powder Characterisation Techniques; assessment;

    Sammanfattning : The KTH Department of Materials Science and Engineering has lacked powder metallurgy research for many years, and as this field is constantly gaining in importance, such research needs to be reestablished. This requires the department to be able to accurately and efficiently characterize the properties of a powder, such as size distribution and composition, and in the short term, this needs to be done using non-specialized equipment.

  7. 5. Karaktärisering, utvärdering och avsättning av Stena Metalls magnetiska fines

    Kandidat-uppsats, Högskolan i Halmstad/Sektionen för ekonomi och teknik (SET)

    Författare :Karin Assarsson; [2014]
    Nyckelord :Shredder residue; Magnetic fines; Recycling; Characterisation; End of life vehicles; : Magnetisk fines; Fragmenteringsrest; Materialåtervinning; Karaktärisering fines;

    Sammanfattning : With a growing population on earth the amount of end-of-life vehicles (ELVs) and other scrap steel increases. The European Directive 2000/53/CE” requires a minimum of 95 % reuse and recovery and 85 % re-use and recycling no later than 1 January 2015, for end-of life vehicles. This imposes a need for more efficient recycling and recovery. LÄS MER
