  1. 6. Analysis of hot workability in 316L steel using ductile fracture criterions

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Viktor Strid; [2022]
    Keywords : Ductile fracture criterion; Finite Element Method; Hot working; 316L Stainless Steel; Fracture Modeling; Gleeble; Hot deformation;

    Abstract : The focus of this thesis is to develop a simulation model for predicting ductile fractures during hot working at Alleima. The main fracture mechanism in these conditions is ductile fracture by void coalescence. The ductile fractures are caused by the linking of voids that appear when there is large plastic deformation near second-phase particles. READ MORE

  3. 7. Alloy adaptation towards accepting higher amounts of secondary material

    University essay from Jönköping University/JTH, Material och tillverkning

    Author : Nikhil Itagi; Shubham Kadam; [2022]
    Keywords : Aluman-16; Phase diagram; Phases; Microstructure; ThermoCalc; Intermetallic; Fractography.;

    Abstract : The work presented aims to find microstructure and mechanical properties after remelting of aluman-16 alloy by using high pressure die casting (HPDC). Alloy has been casted with specific composition. The alumna-16 alloy has been casted in 2 different composition of different Si content of 0.22% and 0. READ MORE

  4. 8. FE Simulation of protective insulation of catalysts in exhaust after-treatment systems of trucks and buses : Investigation and characterization of catalytic converter support mat material for accurate modeling in finite element simulations

    University essay from

    Author : Manroop Bhattasali; [2022]
    Keywords : Catalytic converter; packaging mats; support mats; compression; friction; hyperelastic; hyperfoam; viscoelastic; canning; finite element;

    Abstract : The increase of new and ever more stringent emission legislation has brought about with it a surge in the demand for more sustainable automotive solutions. This has particularly been the case for automobiles, including heavy-duty vehicles like trucks and buses, with internal combustion engines, which now require the design and manufacturing of more durable and reliable components.

  5. 9. Influence of hydrogen and carbides on high temperature cracking in cast Inconel

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Gunnar Dufwa; [2022]
    Keywords : Hydrogen embrittlement; carbide; finite element method; dislocation dynamics;

    Abstract : Hydrogen embrittlement is a well-known source of cracking in metallic mechanical elements. This work studies the influence of hydrogen and carbides on the crack formation in a castnickel-alloy-component in a selective catalytic reduction system. READ MORE

  6. 10. Modelling Magnetism of hcp Iron under Earth’s Inner Core Conditions : Based on first-principle DFT calculations and Machine Learning

    University essay from Linköpings universitet/Teoretisk Fysik

    Author : Linda Le; [2022]
    Keywords : Machine learning; Earth’s Inner Core; hcp Iron; Electronic structure magnetism; Density functional Theory; Local magnetic moments; Ab initio molecular dynamics; ASD-AIMD-MLLSF simulation;

    Abstract : The structure of Earth’s core remains largely a mystery. The solid inner core is believed to exist in extreme pressure and temperature conditions comparable to 300 GPa and 6000 K and consists mainly of iron, Fe. READ MORE
