  1. 1. Dependence of Degradation Mechanisms in Magnesium Alloys on Grain Orientation and Interfaces in 3D

    University essay from Lunds universitet/Materialteknik

    Author : Johan Ranstad; [2023]
    Keywords : Mg-Zn alloys; Diffraction contrast tomography; Isothermal Calorimetry; Immersion testing; Corrosion Rate; Microgalvanic coupling.; Technology and Engineering;

    Abstract : Magnesium alloys are promising candidates as biomedical implants. However, a good understanding of their degradation processes is lacking. In this work, degradation in two magnesium alloys were studied in a simple physiological-fluid electrolyte of H2O+0.9wt%NaCl, Mg-5wt%Zn (Z5) & Mg-5wt%Zn-0. READ MORE

  3. 2. Microstructural evolution of ice under simple shear deformation

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Carina Liebl; [2021-01-11]
    Keywords : ;

    Abstract : To investigate microstructure in ice deformed under simple shear conditions experiments were performed with artificial polycrystalline ice and natural ice samples form Vatnajökull glacier in Iceland. A new deformation apparatus was tested and results from deformation were compared to literature to validate the method. READ MORE

  4. 3. Different Heat Treatment parameters investigation on microstructure, mechanical and wear properties of Hadfield Steel

    University essay from Lunds universitet/Industriell Produktion

    Author : Rahul Milind Kulkarni; Vishwajit Vishnu Kolekar; [2021]
    Keywords : Hadfield Steel; Heat Treatment; Microstructural evolution; Carbides; Austenitization temperature; Technology and Engineering;

    Abstract : Hadfield Steels make up a significant group of steels that can perform with their higher strength, excellent wear resistance, and good formability. To achieve this distinctive behavior along with the alloy compositions, heat treatment is also a vital factor. READ MORE

  6. 5. Understanding the effect of temperature and time on Gamma prime coarsening for Nickel-base superalloy Haynes 282

    University essay from KTH/Materialvetenskap

    Author : Kevin Vattappara; [2019]
    Keywords : Haynes 282; gamma prime 𝛾′ ; Arc-heat treatment; COMSOL modelling; isothermal transformation; coarsening; Thermo-Calc simulations;

    Abstract : Haynes 282 is a gamma prime (𝛾′)-strengthened nickel base superalloy developed in 2005, exhibiting a good combination of high temperature properties and fabricability. Microstructural features such as 𝛾′ and carbides play an important role in deriving the mechanical properties of the alloy during heat treatment. READ MORE
