  1. 1. Machinability study on GCI brake discs - Effects of material variations and process behavior on tool life

    Uppsats för yrkesexamina på grundnivå, Lunds universitet/Industriell Produktion

    Författare :Christian Jaunviksna; [2023]
    Nyckelord :Metal cutting Machinability Grey cast iron Tool wear Cutting data Hardness Microstructure Segmentation; Technology and Engineering;

    Sammanfattning : Grey cast iron is one of the most used materials in the automotive industry. The material has a range of properties that makes it suitable for machining applications, but manufacturers still experience machinability problems. LÄS MER

  3. 2. Infuence of matrix and alloying on the fatigue crack propagation and fracture toughness of compacted graphite iron for cylinderheads

    Master-uppsats, Linköpings universitet/Konstruktionsmaterial

    Författare :Leny Gonzalez; [2020]
    Nyckelord :compacted iron cylinder head fracture toughness fatigue crack propagation alloying;

    Sammanfattning : The constants modernization in the fuels used request improvements in the combustioneffectiveness, as a consequence the material for components as the cylinder heads mustenhance their properties. Seven different compositions of compacted graphite iron (CGI)are analysed with the aim of characterized and select the most suitable material for thecylinder head service condition. LÄS MER

  4. 3. Influence of matrix and alloying on the high cycle fatigue properties of compacted graphite iron for cylinder heads

    Master-uppsats, KTH/Hållfasthetslära

    Författare :Erik From; [2020]
    Nyckelord :;

    Sammanfattning : Continued improvements in combustion processes, introduction of biofuels, decreasing fuel consumption and increasing specific power will inevitably lead to an increase of the combustion pressure, which can be accompanied with a temperature increase. This will increase the loading on many components and drives the development of materials more resistant to the harsh conditions close to the engine. LÄS MER

  5. 4. Relation Between the Material in Press Hardening Dies and Fully Martensitic Transformation : Sheet properties of thick 3D-sheets in small series production

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Jesper Christensson; [2020]
    Nyckelord :hot stamping; press hardening; material properties;

    Sammanfattning : This report evaluates the influence of the die material on the cooling rate and martensitic transformation of press hardened sheets. The goal was to increase the thicknesses of sheets that can form fully martensitic microstructure when press hardened. LÄS MER

  7. 5. Strain Rate Effect on Fracture Mechanical Properties of Ferritic-Pearlitic Ductile Iron.

    Magister-uppsats, Linnéuniversitetet/Institutionen för byggteknik (BY)

    Författare :Firas Almaari; Essam Aljbban; [2018]
    Nyckelord :Ductile Iron; Dynamic Three Point Bending Test; Strain Rate; Fracture Energy.;

    Sammanfattning : This study investigates the effect of strain rate on fracture properties of Ferritic-Pearlitic Ductile Iron. A series of dynamic three point bending tests, with various load application rates, are conducted on Charpy V-notch specimens, in room temperature and approximately -18 °C. LÄS MER
