1. 1. Precipitation analysis in bearing steel Hybrid 60

   University essay from KTH/Materialvetenskap

   Author : Rebecca Rosén; [2023]
   Keywords : martensitic steel; secondary hardening; precipitation; PRISMA; martensitiskt stål; sekundärhärdning; utskiljning; PRISMA;

   Abstract : New materials are always being developed to get the best properties possible where needed. The way to create these materials and test them is also developing. When it comes to high-strength steels, a martensitic microstructure is a common choice. READ MORE

3. 2. Optimization of the process-route of a Nickel-base alloy : Investigation of Sigma-phase precipitation in heat treatment

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Author : Felix Andersson; [2023]
   Keywords : Sigma-phase; austenitic stainless steel; Nickel-base alloy; heat treatment; Sigmafas; austenitiskt rostfritt stål; Nickelbas legering; värmebehandling;

   Abstract : 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. READ MORE

4. 3. 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.

5. 4. 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

6. 5. Modelling of precipitation in an Fe-C-Cr alloy

   University essay from KTH/Materialvetenskap

   Author : Johan Frisk; [2019]
   Keywords : ;

   Abstract : Precipitation modelling is interesting from both an academic and an industrial point of view. Such modelling tools may be used in the field of integrated computational materials engineering (ICME) for design and optimization of material properties. READ MORE
