  1. 11. Modeling of the Stainless Steel Tube Extrusion Process

    Författare :Sofia Hansson; Erman Tekkaya; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Extrusion; FEM; Stainless steel; Tube; Simulering av extrusion av rostfria rör; Material Mechanics;

    Sammanfattning : Seamless tubes of stainless steel can be extruded using glass as a lubricant in the Ugine-Sejournet process. The process is performed at high temperature and is associated with large deformations and high strain rates. LÄS MER

  3. 12. Stainless steel box columns in fire : analysis and design recommendations

    Författare :Björn Uppfeldt; Olivier Vassart; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : The use of stainless steel in buildings is small but increasing, mainly due to the low maintenance costs, favourable corrosion resistance and aesthetic appearance. It is well known that stainless steel also performs better than carbon steel at elevated temperatures. LÄS MER

  4. 13. Patch loading of stainless steel girders : experiments and finite element analyses

    Författare :Emma Unosson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

    Sammanfattning : This thesis deals with the behaviour of stainless steel girders subjected to patch loading. The current loading situation arises for example at beam- column connections or at crane girders where the load is travelling along a girder. At bridge launching it is also important to consider patch loading. LÄS MER

  5. 14. The influence of tool steel microstructure on galling

    Författare :Patrik Karlsson; Pavel Krakhmalev; Anders Gåård; Bojan Podgornik; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Galling; Microstructure; Material transfer; Tool steel; Stainless steel; Metall transfer; Materialteknik; Materials Engineering;

    Sammanfattning : In sheet metal forming (SMF) of materials such as stainless steels there is a major problem with transfer and accumulation of sheet material to the metal forming tool surface. The problem is known as galling; a sort of severe adhesive wear, which results in severe scratching of produced parts. LÄS MER

  7. 15. The Influence of Composition and Hot Processes on Heat Affected Zone and Weld Metal Behavior and Mechnacal Properties of Ti Grade 5 and Stainless Steel

    Författare :Esa Kivineva; KTH; []
    Nyckelord :Stainless steel; Duplex stainless steel; Titanium Grade 5; Ti-6Al-4V; Microstructure; Mecjhanical properties; Welding; Welding simulation;

    Sammanfattning : This thesis discusses on results of experiments carried outwith austenitic, duplex and super duplex stainless steels andTi-6Al-4V. In these it has been seen that the heat cycle duringwelding or weld simulation has a great effect on the propertiesof thematerials. LÄS MER
