  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. Quantifying the Swiss Custom Strategy and Its Impact on Economic Development from 1870 to 1913

    Master-uppsats, Lunds universitet/Ekonomisk-historiska institutionen

    Författare :Noa Gino Reggiani; [2023]
    Nyckelord :Business and Economics;

    Sammanfattning : The late 19th century witnessed a remarkable surge in globalization, resulting in a substantial flow of goods, labour, and capital across national and continental borders. Switzerland, despite its limited domestic market and resource constraints, capitalized on this era of globalization and transformed itself from a relatively impoverished agrarian state to one of the world's wealthiest nations.

  4. 3. Historical mining of Fe-Ca ore in Garpenberg, Sweden. : A study based on lake sediment geochemistry from Finnhytte-dammsjön.

    Kandidat-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Morgan Eliasson; [2023]
    Nyckelord :Paleolimnology; Lake sediment; XRF; Garpenberg; Mining history;

    Sammanfattning : It is well established that mining and metallurgy on a larger scale in Sweden originated in Bergslagen. The historical mining district Garpenberg in Bergslagen presently show the oldest signs of mining in Sweden (2300 BP) based on a study of a lake sediment profile from Gruvsjön. LÄS MER

  5. 4. Simulation and Experimental Based Hardenability Evaluation of Chromium Alloyed Powder Metal Steels

    Master-uppsats, KTH/Materialvetenskap

    Författare :Atharva Kotasthane; [2023]
    Nyckelord :Hardenability; Martensite; Simulation Modelling; Microhardness; Microstructure; Härdbarhet; Martensit; Simuleringsmodellering; Mikrohårdhet; Mikrostruktur;

    Sammanfattning : Powder metallurgy is a branch of metal forming technology where metal powders are used to manufacture parts and components. It is a flexible and economical technique for manufacturing complicated shapes. This present work focuses on press and sinter technology and forms a part of Höganäs’s efforts of modelling hardenability through quenching. LÄS MER

  7. 5. Optical Emission Spectroscopy Pulse Distribution Analysis on Steel Production Samples : Accuracy, sample variation, spread in different samples and steel grades/routes

    Master-uppsats, KTH/Materialvetenskap

    Författare :Paulo Urrea Molina; [2023]
    Nyckelord :;

    Sammanfattning : This thesis work aimed to contribute to the development of online characterization techniques for non-metallic inclusions in steelmaking. The study focused on assessing the precision and accuracy of the optical emission spectroscopy pulse distribution analysis (OES/PDA) technique using asreference light optical microscope (LOM) and scanning electron microscope(SEM).
