  1. 1. Influence from temperature variations in stacking fault energy on the mechanical properties of stainless steels

    University essay from KTH/Materialvetenskap

    Author : Christopher Hallén; Marcus Johansson Storne; [2023]
    Keywords : ;

    Abstract : This paper investigates the mechanical properties and deformation mechanisms of austenitic stainless steels and how they relate to the material property of stacking fault energy (SFE) and its relation to temperature and nickel content. Austenitic stainless steels are commonly used and well known for good mechanical properties and deformation characteristics. READ MORE

  3. 2. The Investigation of Crack Propagation in Cortical Bone using a Phase Field Fracture Approach

    University essay from Lunds universitet/Avdelningen för Biomedicinsk teknik

    Author : Olivia Karlsson; [2022]
    Keywords : Cortical Bone; Cortical bone microstructure; Phase field; Phase field fracture approach; Crack propagation; Technology and Engineering;

    Abstract : Human cortical bone tissue is a complex and strong composite material, with the ability to resist damage via slowing, stopping or redirecting propagating cracks. However, the ability is impaired with age. At the microscale, changes are seen both in terms of increased porosity and as changes in local material parameters. READ MORE

  4. 3. Mechanical and tribological characterization of additive manufactured Co-alloyed tool steels aimed for cutting tool bodies

    University essay from Högskolan Dalarna/Institutionen för information och teknik

    Author : Jijesh Rajan; [2022]
    Keywords : Maraging steels; Selective laser melting; microstructure; wear; Modified 18Ni300; Osprey MAR;

    Abstract : A drill tool body operates under tough cutting conditions where it is subjected to severe rubbing at the drill flute margin by the sliding chips. The tool wear caused by the contact stresses of the high-speed sliding chips is one of the common damage mechanisms observed in drill tool bodies. READ MORE

  5. 4. Impact of wood fibers on the mechanical performance of biocomposite materials

    University essay from Lunds universitet/Institutionen för byggvetenskaper; Lunds universitet/Hållfasthetslära

    Author : Jose Maria Moreno Ivañez de Lara; [2021]
    Keywords : Biocomposite; Composite; X-ray tomography; Image analysis; Injection moulding; Fracture mechanisms; Technology and Engineering;

    Abstract : Plastics are amazing materials with outstanding properties that make them very useful and cheap for a wide range of uses. However, their pollution to the environment has become one of the main problems to solve in this century. In this Master Thesis biocomposites from Biofiber Tech are studied. READ MORE

  6. 5. Erosion Behaviour of Thermal Barrier Coatings

    University essay from Linköpings universitet/Konstruktionsmaterial

    Author : Caroline Wännman; [2021]
    Keywords : erosion; TBC; APS; EB-PVD; PS-PVD; failure mechanisms;

    Abstract : Thermal barrier coatings (TBCs) are advanced material systems used in the hot sections of gas turbines. The TBCs are designed to provide insulation against hot gases by a ceramic top coat and to provide oxidation and corrosion resistance by a metallic bond coat. READ MORE
