1. 1. Precipitation behavior of the super austenitic stainless steel SANICRO® 35 and the effect on impact toughness and pitting corrosion resistance

   University essay from KTH/Materialvetenskap

   Author : Shunyi Li; [2022]
   Keywords : Super austenitic stainless steel; solid phase transformation; TTT diagram; impact toughness; critical pitting temperature; TC PRISMA simulation; Superaustenitiskt rostfritt stål; fastfasomvandling; TTT-diagram; slaghållfasthet; kritisk punktfrätningstemperatur; TC PRISMA simulering;

   Abstract : This research extended the knowledge of the solid phase transformation and the resulting influence on impact toughness and pitting corrosion resistance in super austenitic stainless steel (SASS) SANICRO® 35. A time-temperature-transformation diagram (TTT diagram) was assembled by performing isothermal heat treatments in the temperature range of 650-1050 °C for different periods of time, ranging from 5 min to 500 min.

3. 2. Characterization of Secondary Carbides in Low-Alloyed Martensitic Model Alloy Tool Steels

   University essay from KTH/Materialvetenskap

   Author : Jubica Jubica; [2020]
   Keywords : martensitic steel; secondary hardening; precipitation; STEM; EDS; Prisma; size distribution; martensitiskt stål; sekundärhärdning; utskiljning; STEM; EDS; PRISMA; storleksfördelning;

   Abstract : The development of tool steels for making and shaping other materials requires a better understanding of the material's properties during manufacture. These high-quality steels include many alloying elements, which give increased hardness during tempering. For producing hardened microstructures, austenite generation is essential. READ MORE

4. 3. 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

5. 4. Precipitation during Tempering of Martensite in Fe-Cr-C alloys

   University essay from KTH/Materialvetenskap

   Author : Chanachon Techaboonanek; [2012]
   Keywords : precipitation; microstructure; tempered martensite; Fe-C-Cr alloys; carbide; simulation;

   Abstract : The martensite structure is the most important microstructure in tool steel due to its high hardness. However, a lack of ductility is the major drawback. In order to improve the ductility and still maintaining a suitable hardness a tempering process is needed. READ MORE
