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

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Christopher Hallén; Marcus Johansson Storne; [2023]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

    Sammanfattning : 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. LÄS MER

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

    Master-uppsats, KTH/Materialvetenskap

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

    Sammanfattning : 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. LÄS MER

  7. 5. Cryogenic properties of additive manufactured austenitic stainless steels for space applications

    Master-uppsats, Luleå tekniska universitet/Materialvetenskap

    Författare :Patricio Piantanida; [2023]
    Nyckelord :austenitic stainless steel; additive manufacturing; cryogenic;

    Sammanfattning : The mechanical properties of three austenitic stainless steel alloys, namely 21-6-9, 316L and a modifed 316, fabricated via laser powder bed fusion, have been studied. From the results previously obtained through tensile tests at room and cryogenic temperatures, their strength and ductility were compared against similar conventionally processed materials. LÄS MER
