  4. 3. Challenges and Metallurgical Benefits of Implementing Metal Additive Manufacturing : A Case Study on Excavator Bucket Teeth Comparing Sand Casting with Additive Manufacturing

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Sam Thai; Michael Thunberg; [2023]
    Nyckelord :Challenges; Electron Beam Melting; Metal Additive Manufacturing; Metallurgy; Microstructure; Porosity; Qualification; Sand Casting;

    Sammanfattning : Introduction: Production systems go through changes over time and there are different factors driving the change. Metal Additive manufacturing (AM) could be a factor with industries that already havetaken interest in the manufacturing technique. LÄS MER

  5. 4. Process characterisation of an additive manufacturing equipment : An analysis of the effect of electron beam powder bed fusion process parameters on the melt pool geometry and microstructure of Ti-6Al-4V

    Master-uppsats, Linköpings universitet/Konstruktionsmaterial

    Författare :Ida Ljusell; [2023]
    Nyckelord :Additive manufacturing; AM; 3d printing; titanium; process characterisation; electron beam powder bed fusion;

    Sammanfattning : Additive manufacturing (AM) are manufacturing methods where components are produced by adding material layer by layer which allows for a high freedom of design as well as little or no material waste compared to conventional manufacturing methods. Despite the many benefits of AM there are still problems concerning the quality of the produced material. LÄS MER

  7. 5. 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.
