  1. 1. Fracture analysis of tensile- and fatigue failure for perforated and wedge wire structures

    University essay from

    Author : David Barjosef; Alexander Austen Öhrn; [2022]
    Keywords : ;

    Abstract : In the effort to produce more durable filters and understand their mechanical failure, this study presents distinctive indicators on the cause of failure for welded perforated- and wedge wire sheets in 316L stainless steel, super duplex UR52N stainless steel and grade 2 titanium. The study achieves this by fracture analysis on specimens from tensile strength- and fatigue testing. READ MORE

  3. 2. Microstructural characterization of quench annealed duplex SAF 2507 utilizing EBSD

    University essay from Uppsala universitet/Tillämpad materialvetenskap

    Author : Simon Beyermann; [2022]
    Keywords : sigma phase; chi phase; electron backscatter diffraction; super duplex stainless steel; recrystallization; SAF 2507 UNS S32750 .;

    Abstract : Producing large bars of duplex stainless steel free from precipitated embrittling phases isdifficult due to the many factors that influence precipitation. Research shows that intermetallicslike sigma and chi deteriorate principal material properties for the main application areas. READ MORE

    University essay from

    Author : Adrian Falk; [2017]
    Keywords : Marin tillväxt; superduplex; bottenfärg; havstulpaner;

    Abstract : Some of the world’s most ancient, but still viable, organisms have since the beginning of maritime caused problems for the industry. The problems affect both the longlivety and efficiency of ships which is caused by the mere presence of organisms attached to the ship hulls. READ MORE

  5. 4. Bow design for operation in brash ice

    University essay from KTH/Marina system

    Author : Kjell Teepen; [2017]
    Keywords : ;

    Abstract : Using a vessel for public transport can possibly save large amounts of time in a city as Stockholm. The transport is easy during the period of the year where there is no ice cover on the waters, however during the time when there is ice, the vessels used face more extreme conditions. READ MORE

  6. 5. Modelling of the temperature field in TIG arc heat treated super duplex stainless steel samples

    University essay from Högskolan Väst/Avdelningen för maskinteknik och naturvetenskap

    Author : Chamara Kumara; [2016]
    Keywords : CFD modelling; Heat affected zone; OpenFOAM; Temperature field; TIG weld-ing; Phase transformation;

    Abstract : Super Duplex Stainless Steels have superior corrosion resistance properties and strength compared to conventional steels. However, these properties are influenced by the different phases that precipitate during the heat treatment process. READ MORE
