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

    Master-uppsats, KTH/Materialvetenskap

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

    Sammanfattning : 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. LÄS MER

  3. 2. Modelling of the temperature field in TIG arc heat treated super duplex stainless steel samples

    Master-uppsats, Högskolan Väst/Avdelningen för maskinteknik och naturvetenskap

    Författare :Chamara Kumara; [2016]
    Nyckelord :CFD modelling; Heat affected zone; OpenFOAM; Temperature field; TIG weld-ing; Phase transformation;

    Sammanfattning : Super Duplex Stainless Steels have superior corrosion resistance properties and strength compared to conventional steels. However, these properties are influenced by the different phases that precipitate during the heat treatment process. LÄS MER
