  1. 1. Development of Nickel-Titanium Shape Memory Alloys using Electron Beam Melting

    Master-uppsats, KTH/Materialvetenskap

    Författare :Georgios Manolios; [2022]
    Nyckelord :;

    Sammanfattning : In this project, the effect of electron beam melting on the behavior of NiTi shape memory alloyshas been studied, with focus on the effects of recycling powder within the process and theprocess parameters used and how “smoking” is affected. Flowability, powder characteristicsand chemical composition have been evaluated using imaging analysis techniques, Hallflowmeter measurements, FT4 powder rheometry and energy dispersive X-ray spectroscopyboth in virgin powder and in recycled powders.

  3. 2. Characterization of Metal Powders in Electron Beam Powder Bed Fusion : Regarding particle size distribution of the finished part

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Mattias Jerhamre Engström; Saman Sharif Hedås; [2022]
    Nyckelord :;

    Sammanfattning : As the manufacturing industry looks for better ways to create complex parts using sustainable and efficient methods, the additive manufacturing sector is taking a step forward. Additive manufacturing brings with it a large reduction in material used and the complex structures that can be created are not something to overlook. LÄS MER

  4. 3. 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.

  5. 4. Characterization of uranium oxide powders and sinterability

    Master-uppsats, KTH/Kemiteknik

    Författare :Joakim Ceder; [2021]
    Nyckelord :uranium dioxide; sinterability; reduction; pore former; chemical activity; urandioxid; sintringsaktivitet; reduktion; porbildare; kemisk aktivitet;

    Sammanfattning : Uranoxid (UOx) är ett energitätt material som ofta används i kärnbränsle. UOx-pulver pressas och sintras för att tillverka urandioxidkutsar som förs in i bränslestavar. Stavarna monteras slutligen ihop till ett bränsleknippe. Tillverkningsprocessens stabilitet och förutsägbarhet är viktiga. LÄS MER

  7. 5. Influence of slurry viscosity on cemented carbide powder properties

    Master-uppsats, KTH/Materialvetenskap

    Författare :Isha Anirudha Patankar; [2020]
    Nyckelord :Cemented carbide powder; Slurry viscosity; Spray drying process; Powder characterization; Hårdmetallpulver; Slamviskositet; Spraytorkning; Pulverkarakterisering;

    Sammanfattning : Cemented carbide powder production is the first step in the manufacturing of cemented carbide inserts.The quality of the powder affects the successive process steps in the production of the cemented carbide inserts. The powder is produced by spray drying of a slurry. The slurry consists of polymer, water, ethanol, and dry components. LÄS MER
