  1. 1. The Effect of Alternative Tungsten Carbide Grain Size Distribution on Microstructure and Mechanical Properties in Cemented Carbides

    Master-uppsats, KTH/Materialvetenskap

    Författare :Filip Ivarsson; [2022]
    Nyckelord :Cemented Carbides; WC Grain Size Distribution; Mechanical Properties; Microstructure Analysis; Hårdmetall; WC Kornstorleksfördelning; Mekaniska Egenskaper; Mikrostruktur Analys;

    Sammanfattning : In the constant pursuit of better-performing cemented carbides, recent studies suggest that a combination of better hardness and toughness can be obtained by changing its WC grain size distribution. As the area is still rather unexplored, this  thesis  aims  to  broaden  the  knowledge  and  answer  whether mechanical properties can be changed by changing the WC grain size distribution, in the context of mining drill bit inserts.

  3. 2. Product Variety Cost in an Engineering-to-Order Business

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Filip Ivarsson; August Åström; [2021]
    Nyckelord :Engineering-to-Order; Product Variety; Variation; Cost Drivers; Activity-Based Cost Calculation; Process Mapping; Standardisation;

    Sammanfattning : Engineering-to-order is a production approach that aims to develop each customer order from scratch based on specific requirements, and is therefore inevitably characterised by a high product variety. It is clear that this strategy is costly, but previous research is lacking in terms of providing real-life data regarding how a high product variety affects costs. LÄS MER

  4. 3. Trådlös dynamisk lastbalansering

    Uppsats för yrkesexamina på grundnivå, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Joakim Turesson; Filip Ivarsson; [2021]
    Nyckelord :Lastbalansering; Dynamisk lastbalansering; Z-Wave; BLE; Bluetooth Low Energy; Smarta hem; Gateway; Trådlös lastbalansering; Trådlös dynamisk lastbalansering; Raspberry Pi;

    Sammanfattning : The purpose of this project was to create a gateway between a Z-Wave device and a Bluetooth device.The gateway is supposed to make it possible for the company AES AB to sell and install a dynamic load balancer to their EV charger, even after it’s already been installed.

  5. 4. Crucial Parameters for Additive Manufacturing of Metals : A Study in Quality Improvement

    Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Lina Berglund; Filip Ivarsson; Marcus Rostmark; [2019]
    Nyckelord :Additive manufacturing; Production parameters; Sandvik; Quality improvement; Selective laser melting; Powder bed fusion; Process control;

    Sammanfattning : Production by Additive Manufacturing creates opportunities to make customized products in small batches with less material than in traditional manufacturing. It is more sustainable and suitable for niche products, but entails new production demands to ensure quality. LÄS MER

  7. 5. Characterization of Fe-rich skarns and fluorapatite-bearing magnetite occurrences at the Zinkgruvan Zn-Pb-Ag and Cu deposit, Bergslagen, Sweden

    Master-uppsats, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Filip Ivarsson; [2019]
    Nyckelord :Zinkgruvan; Bergslagen; Magnetite; REE; Broken Hill-type; Skarn; SEDEX;

    Sammanfattning : Zinkgruvan is a stratiform Zn-Pb-Ag and Cu sulphide deposit hosted by Paleoproterozoic strata in southern Bergslagen, Sweden. The deposit underwent medium-high grade regional metamorphism during the Svecokarelian orogeny, including partial melting of the host succession. LÄS MER
