  1. 1. Possibilities of Reducing Internal Scrap Rates and Increase Scrap Recyclability of Dilute Copper Alloys from Vertical Upwards Continuous Cast (VUCC) Process

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Minna Olsson; [2023]
    Nyckelord :metallurgy; copper; alloy; continuous casting; materials chemistry; Technology and Engineering;

    Sammanfattning : Copper and copper alloys are important material systems for the electrification of society. The high workability of the materials makes them appropriate in numerous different applications which require highly conductive properties. LÄS MER

  3. 2. Studie av syretillgångens inverkan på nötning av hårdmetall vid bearbetning av kopparlegeringar

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Julia Rosengren; [2023]
    Nyckelord :tribologi; nötning; hårdmetall; mässing;

    Sammanfattning : During the production of metal zippers, cemented carbide (CC) tools are used to cut preformed brass wire into small elements. Even though the cemented carbide is much harder than the copper alloy, it gets worn and eventually the tool must be replaced. LÄS MER

  4. 3. Evaluation of a novel method to investigate diffusion between copper-zinc alloys and cemented carbides

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :André Larsson; [2022]
    Nyckelord :Diffusion; Brass; Copper alloys; Copper zinc alloys; Wear; Cemented carbide; Diffusion couple;

    Sammanfattning : When slow wear mechanisms are studied it is important to examine slower processes, such as diffusion. Such processes can have a significant impact over time and can cause other phases to form, which can have a large effect on the wear. LÄS MER

  5. 4. Vikingatida förgyllningstekniker : En studie av förgyllningstekniker tillämpade på föremål från Birka med SEM-EDS

    Master-uppsats, Stockholms universitet/Arkeologiska forskningslaboratoriet

    Författare :Amanda Patriksdotter; [2019]
    Nyckelord :Gilding; Viking age; Birka; SEM-EDS; archaeometallurgy;

    Sammanfattning : Studies with primary focus on Viking age gilding techniques in Scandinavia has not been carried out since the sixties. During the past 50 years knowledge about prehistoric gilding techniques and traces of them in the archeological material, as well as the usage of natural sciences within archaeology, has developed considerably.

  7. 5. Optimization of the AdBlue e vaporation module for Scania V8 engines

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Mattia Antoniotti; [2017]
    Nyckelord :CR; evaporation unit; urea deposits; heat fins; Urea; förångningsmodulen; ureaavlagringar; rörflänsar;

    Sammanfattning : The aftertreatment techniques introduced to follow the emission legislations require a constant improvement process to comply with the gradually more stringent demands. SCR is the system used nowadays to deal with NOx emissions in most heavy-duty vehicles. LÄS MER
