  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

  3. 2. MODELLING OF HEAT TRANSFER OF RAILWAY SWITCH HEATING

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Siddharth Suresh Sumathi; [2023]
    Nyckelord :Conjugate Heat transfer analysis; transient analysis; CFD; insulation; measurement data uncertainties.; Konjugat Värmeöverföringsanalys; transientanalys; CFD; isolering; mätdata osäkerheter.;

    Sammanfattning : Switches and crossings are vital components of the railway network. Obstacles to the smooth functioning of these components could result in delays and network traffic. Given the geographical location of Sweden, snow is one of the major obstacles for the switches. LÄS MER

  4. 3. 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

  5. 4. A Balancing Act : Understanding the Gap Between Experienced Realities and The EU Policies Towards the Eradication of Trafficking in Human Beings Through an Ontological (In)Security Lens

    Master-uppsats, Malmö universitet/Institutionen för globala politiska studier (GPS)

    Författare :Lisa Vervoort; [2023]
    Nyckelord :Human Trafficking; Ontological Security; European Union;

    Sammanfattning : The issue of human trafficking is, as stated by the EU, a crime that alters the fabric of our society and is a severe violation of human rights. However, the migration crisis within the EU has fueled a rise of the right across the continent. LÄS MER

  7. 5. Development and analysis of fire suppresion during steel quenching : Three paths of analysis of fire- and smoke suppresion during steel hardening processes

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

    Författare :Alex Eidersjö; [2023]
    Nyckelord :Product development; Produktutveckling;

    Sammanfattning : This thesis looks at an issue of excessive fire and smoke development during open tank quenching. The quenching in question being done as part of a hardening process of steel springs during manufacturing at Lesjöfors Fjädrar AB. The thesis was written under supervision of of Rejlers Sweden AB.
