   Sammanfattning : The focus of this master’s thesis is on the heat treatment of Ni-base alloys, specifically the risk of intermetallic σ-phases during different stages of heat treatment. The alloy studied is Sanicro®28, a super-austenitic stainless steel produced by Alleima AB. LÄS MER

3. 2. 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
