  1. 1. High Temperature Tribology of Exhaust Components in Alternative Fuel Engines

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Muhammad Hashir Zaheer; [2023]
    Nyckelord :High temperature tribology; Wear; Friction; Exhaust manifold; Lip seal ring; Wear resistant coatings; Inconel 718c; SiMo51 ductile cast iron; AlTiN; Tribaloy 400;

    Sammanfattning : Internal Combustion Engine (ICE) exhaust components are exposed to extreme operating temperatures. Thus, it is necessary that they are designed with materials that can sustain thermal and vibrational stresses. LÄS MER

  3. 2. Chip Management in Milling and Drilling of Ductile Cast Iron

    Master-uppsats, Lunds universitet/Industriell Produktion

    Författare :Alexander Jönsson; Giacomo Aliboni; [2023]
    Nyckelord :Chip Carryover; Chip Management; Ductile Cast Iron; Chip Removal; Chip Asportation; Milling; Drilling; Technology and Engineering;

    Sammanfattning : This paper presents a comprehensive cross-functional analysis of machining operations for ductile cast iron components in the automotive industry, focusing on the problem of chip carryover and its impact on downstream processes. The research aims to understand the role of machining and identify the source of the issue, by analyzing different machining sequences and the chips that affect the final product or subsequent production stages.

  4. 3. Use of Thermal Analysis to reduce the Microporosity in ductile iron. : Analysis of micro porosity casting defect

    Master-uppsats, Jönköping University/JTH, Material och tillverkning

    Författare :Adriana Mura; [2022]
    Nyckelord :Nucleation; Ductile Cast iron; Inoculation; Preconditioning; Over-inoculation; Charge materials; Hypoeutectic; Eutectic; Hypereutectic; Shrinkage;

    Sammanfattning : It became always more important in Cast Iron Foundry to have a process control system that helps to reduce the variability and follow the correct specifications, to simplify the detection of eventual inoculation problems or incorrect working ranges.In the thesis, it is presented a case study of a specific defect of microporosity that appeared in the internal areas of some castings.

  5. 4. Variations in material properties of grey cast iron and its impact on tool wear

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell Produktion

    Författare :Andreas Söderholm; [2021]
    Nyckelord :Grey cast iron; hard inclusions; tool wear; machinability; graphite structure.; Technology and Engineering;

    Sammanfattning : Among cast materials, grey cast iron and ductile iron makes up about three quarters of all cast parts. This makes the manufacturing and machining of grey cast iron an important economical factor for the automotive industry. LÄS MER

  7. 5. Three-dimensional modelling of the Källfallsgruvan iron oxide deposit, Riddarhyttan ore field, Bergslagen, Sweden: Integrating existing and new data to aid understanding of structural controls and mineral exploration

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

    Författare :Edna Spahic; [2021]
    Nyckelord :Three-dimensional modelling; Mineral exploration; Bergslagen; Riddarhyttan ore field; Källfallsgruvan iron-oxide deposit;

    Sammanfattning : The Bergslagen ore province, located in the Fennoscandian shield in the south-central part of Sweden hosts several metallic mineral deposits, one of them being the Källfallsgruvan iron-oxide deposit in the Riddarhyttan ore field, situated in a high-strain shear belt denoted as the West Bergslagen Boundary Zone (WBBZ).  An accurate 3D geological model of the Källfallsgruvan iron-oxide deposit has been generated to aid understanding of the ore body geometries and calculating volume and tonnage.
