1. 1. Influence from temperature variations in stacking fault energy on the mechanical properties of stainless steels

   University essay from KTH/Materialvetenskap

   Author : Christopher Hallén; Marcus Johansson Storne; [2023]
   Keywords : ;

   Abstract : This paper investigates the mechanical properties and deformation mechanisms of austenitic stainless steels and how they relate to the material property of stacking fault energy (SFE) and its relation to temperature and nickel content. Austenitic stainless steels are commonly used and well known for good mechanical properties and deformation characteristics. READ MORE

3. 2. 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

4. 3. Simulation and Experimental Based Hardenability Evaluation of Chromium Alloyed Powder Metal Steels

   University essay from KTH/Materialvetenskap

   Author : Atharva Kotasthane; [2023]
   Keywords : Hardenability; Martensite; Simulation Modelling; Microhardness; Microstructure; Härdbarhet; Martensit; Simuleringsmodellering; Mikrohårdhet; Mikrostruktur;

   Abstract : Powder metallurgy is a branch of metal forming technology where metal powders are used to manufacture parts and components. It is a flexible and economical technique for manufacturing complicated shapes. This present work focuses on press and sinter technology and forms a part of Höganäs’s efforts of modelling hardenability through quenching. READ MORE

5. 4. Combined CALPHAD and Machine Learning for Property Modelling

   University essay from KTH/Materialvetenskap

   Author : Kyle Paulus; [2020]
   Keywords : ;

   Abstract : Techniques to improve the speed at which materials are researched and developed has been conducted by investigating the machine learning methodology. These techniques offer solutions to connect the length scales of material prop- erties from atomistic and chemical features using materials databases generated from collected data. READ MORE

6. 5. Reliable Carburization of AISI H13 Steel : The Impact of Preoxidation

   University essay from KTH/Materialvetenskap

   Author : Martin Palm; [2020]
   Keywords : Preoxidation; Case hardening; Uddeholm Orvar® Superior; Passive oxide layers; Iron oxides; Carbon adsorption;

   Abstract : Case hardened Uddeholm Orvar® Superior (Orvar) has the potential to replace currently used materials in shafts inside transmissions, which would lower the overall weight and thus result in lower fuel consumption while maintaining the necessary mechanical properties. However, previous studies have failed to reliably carburize the steel during the case hardening process. READ MORE
