  1. 21. Determining the Influence of the Type of Shielding Gas during Additive Manufacturing of an Aluminum Alloy by Monitoring the Process Qualitatively and Analyzing Process Byproducts Quantitatively

    Master-uppsats, KTH/Materialvetenskap

    Författare :Stefanie Desiree Kleemeyer; [2021]
    Nyckelord :additive manufacturing; PBF-LB M; aluminum; shielding gas; argon; nitrogen; helium; carbon dioxide;

    Sammanfattning : This thesis analyzes the influence of process gases on the formation and the characteristics of process byproducts that emerge during additive manufacturing of an aluminum alloy belonging to the 2000 series.  In order to address the influence, four pure gases, argon, nitrogen, helium, and carbon dioxide, were used as a shielding gas on the same parameter sets.

    Sammanfattning : Today’s transportation highly depends on hydrocarbon fuels, and reducing the weight could help a lot in reducing the air pollutants and carbon footprints in the environment to comply with the strict regulations set by reputable standard organizations in the world. Utilizing lightweight materials in automobile parts is one of the key factors to succeed in meeting the goals defined in the standards. LÄS MER

  4. 23. Underwater probe for deep sea exploration : Long range acoustic underwater communication system

    M1-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Kim Nykvist; [2020]
    Nyckelord :Acoustic communication; temperature; Expendable Bathythermograph; XBT;

    Sammanfattning : This was a thesis that was commissioned by Researcher Peter Sigray at the Royal Institute of Technology (KTH) in Stockholm and was based on an idea by Professor Thomas Rossby, University of Rhode Island (URI). The idea was to further develop the existing Expendable Bathythermograph (XBT), which has been in use since the 1960s. LÄS MER

  5. 24. Effect of conformal cooling in Additive Manufactured inserts on properties of high pressure die cast aluminum component

    Master-uppsats, Jönköping University

    Författare :Ruslan Sevastopolev; [2020]
    Nyckelord :High Pressure Die Casting HPDC ; Additive Manufacturing AM ; Aluminum Al ; Tensile test; Cooling channels; Conformal cooling; Laser Based Power Bed Fusion of Metals PBF-LB M ; Microstructure; Secondary Dendrite Arm Spacing SDAS .;

    Sammanfattning : Additive manufacturing can bring several advantages in tooling applications especially hot working tooling as high pressure die casting. Printing of conformal cooling channels can lead to improved cooling and faster solidification, which, in turn, can possibly result in better quality of the cast part. LÄS MER

  7. 25. Surface Treatment for Additive Manufactured Aluminum Alloys

    Master-uppsats, Linköpings universitet/Molekylär ytfysik och nanovetenskap; Linköpings universitet/Tekniska fakulteten

    Författare :Marianne Gavelius; Karin Andersson; [2020]
    Nyckelord :Surface treatment; additive manufacturing; Al alloy 2024-T3; Scalmalloy; AlSi10Mg; powder coating; TSA; anodization; SEM;

    Sammanfattning : Manufacturing of aircraft parts is often complex and time-consuming, which has led to an increased interest in new manufacturing technologies in the Swedish industry such as additive manufacturing (AM). Additive manufacturing techniques could be a solution to meet the aircrafts’ demand since it contributes to an efficient manufacturing and allows a just-in-time production of complex metal parts in their final shape.
