  2. 1. Computational Materials Design of Medium Mn Steels

    Author : Fei Huyan; Annika Borgenstam; Peter Hedström; Marcel Somers; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Medium Mn steels (~ 3–10 mass % Mn), a new category of advanced high strength steels, attracted worldwide research interests recent years due to their excellent mechanical properties and low cost. These steels have fine microstructures and contain large fraction of metastable retained austenite (~ 30 volume %), therefore exhibit excellent strength and elongation. READ MORE

    Abstract : Liquid lead as heat transfer fluid presents attractive features for future power technologies, such as next-generation nuclear reactors, thermal solar power, and thermal storage. Liquid lead has excellent heat transfer properties well suited for operating at high temperatures. READ MORE

  6. 4. A Study of Parameters and Properties Influencing the Size, Morphology and Oxygen Content of Water Atomized Metal Powders

    Author : Fredrik Persson; Pär Jönsson; Christopher Neil Hulme; Lauri Holappa; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The production of metal powders by water atomization is a well-established process, which can be used to produce a wide range of particle sizes for different applications. In general, there is a lack of detailed knowledge about what process parameters that affect the powder properties for water atomized metal powders. READ MORE
