    University essay from Lunds universitet/Industriell Produktion

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

    Abstract : 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. READ MORE

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

    University essay from Linköpings universitet/Konstruktionsmaterial

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

    Abstract : 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. READ MORE

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

    University essay from KTH/Hållfasthetslära

    Author : Erik From; [2020]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Jesper Christensson; [2020]
    Keywords : hot stamping; press hardening; material properties;

    Abstract : 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. READ MORE
