  1. 1. Initial utvärdering av lågtemperatur pre-reforming katalysatorer

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Jon Selimi; [2019]
    Nyckelord :catalysis; chemical engineering; kemiteknik; reforming; Technology and Engineering;

    Sammanfattning : The purpose of this project was to perform a screening on catalysts with different formulations for the pre-reforming process. Three of the five catalysts tested were made by the student using the incipient wetness impregnation method. LÄS MER

  2. 2. Modelling the influence of porosity on fatigue strength of sintered steels

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Strukturkemi

    Författare :Emily Hall; [2019]
    Nyckelord :Fatigue; Powder metallurgy; PM; sintered steels; fracture mechanics; porosity; metal powders; fatigue strength; fatigue limit; utmattning; pulvermetallurgi; metallpulver; utmattningsgräns; brottmekanik; porositet; sintring;

    Sammanfattning : The pores in pressed and sintered components constitute weak points in the material since the stress concentration is larger than the nominal stress there. Therefore, fatigue cracks initiate at the pores. Specifically, it can be assumed that the fatigue cracks initiate at the largest pore in the stressed volume. LÄS MER

  3. 3. Metal Filament 3D Printing of SS316L : Focusing on the printing process

    Master-uppsats, KTH/Maskinkonstruktion (Avd.)

    Författare :Karthikesh Gante Lokesha Renukaradhya; [2019]
    Nyckelord :Additive manufacturing; stainless steel 316L; metal-polymer; sintering; Post processing; 3D printer; Additiv tillverkning; rostfritt stål 316L; metallpolymer; sintring;

    Sammanfattning : As a cutting edge manufacturing methodology, 3D printing or additive manufacturing (AM) brings much more attention to the fabrication of complex structure, especially in the manufacturing of metal parts.A number of various metal AM techniques have been studied and commercialized.

  4. 4. QUALITY IMPROVEMENT OF CERAMIC PARTS FORMEDICAL APPLICATIONS THROUGHOPTIMIZATION OF THE ADDITIVE MANUFACTURING ANDPOST-PROCESSING PROCESSES

    Master-uppsats, KTH/Industriell produktion

    Författare :Eva Hofacker; [2018]
    Nyckelord :;

    Sammanfattning : Additive Manufacturing (AM) is beneficial for medical applications in which tissues must be replaced because AM enables the fabrication of highly complex three-dimensional structures. In this study the AM and the post-processing steps of additive manufactured ceramic parts of a specific material for tissue replacement were examined in order to optimize the parts’ quality. LÄS MER

  5. 5. Design of cemented carbide with Ni-based superalloy binder strengthened with y’-Ni3Al precipitates

    Master-uppsats, KTH/Materialvetenskap

    Författare :Oscar Edholm; [2018]
    Nyckelord :Cemented Carbide; Super alloy; Ni-alloy; Ni-Super alloy; Superalloy; Ni3Al; NiAl; Gamma Prime; Gamma; Precipitates; Ni3Al Precipitates; Master Alloy; Liquid Phase Sintering; Cementerad karbid; Hårdmetall; Superlegering; Ni-legering; Ni-Superlegering; Superalloy; Ni3Al; NiAl; Gamma Prim; Gamma; Precipitates; Ni3Al Precipitates; Mästerlegering; Utfällning;

    Sammanfattning : Replacement of cobalt in cemented carbides has gained in attention recently because threats of regulations due to health issues (cancerogenic effect), increased demand from the electric vehicle industry and the questionable extraction from countries like Democratic Republic of Congo. In this report the use of Ni-based binder as an alternative binder for cemented carbides has been explored. LÄS MER
