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. 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.

4. 3. Correlation between microstructure and fatigue cracks in cast aluminium alloy A205

   University essay from Jönköping University/Tekniska Högskolan

   Author : Max Holmberg; Pontus Sundberg; [2022]
   Keywords : Aluminium Alloy A205;

   Abstract : Materials research in the aerospace industry is, among other things, focused on reducing the weight and increasing the life of components. Materials with high strength and long lifespan are therefore examined. READ MORE

5. 4. Linkage of Macro- and Micro-scale Modelling Tools for Additive Manufacturing

   University essay from KTH/Materialvetenskap

   Author : Julia Sjöström; [2020]
   Keywords : Maraging steel; selective laser melting; temperature evolution; macro-scale modelling; segregation; ICME.;

   Abstract : Additive manufacturing methods for steel are competing against commercial production in an increasing pace. The geometry freedom together with the high strength and toughness due to extreme cooling rates make this method viable to use for high-performance components. The desirable material properties originate from the ultrafine grain structures. READ MORE

6. 5. Extraction Replicas of Common Engineering Alloys for Analysis of Small Precipitates

   University essay from KTH/Materialvetenskap

   Author : Monika Rolinska; [2020]
   Keywords : Extraction replica; transmission electron microscopy; materials characterization; precipitation; Extraktionsrepliker; transmissionselektronmikroskopi; materialkaraktarisering; utskiljningar;

   Abstract : Characterization of small precipitates is important for development of new alloys. One inherent  difficulty  in  characterisation  of  small  precipitates  with  electron microscopy techniques  while  the  particles  are  embedded  in  the  matrix,  is  that the surrounding bulk material will contribute to the analysed signal- limiting, for example, the quantification of the composition of particles.
