  2. 1. Plastic Deformation of Duplex Stainless Steel

    Author : Magnus Nyström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; microstructure; plastic zones; impact toughness; anisotropy; prestraining; annealing; fractography; fatigue;

    Abstract : Duplex austenitic/ferritic stainless steels are increasingly used as an alternative to conventional austenitic grades. Main advantages of the duplex grades are good resistance to corrosion cracking and corrosion fatigue in environments that contain chloride. READ MORE

  5. 3. Transformation phenomena in a super duplex stainless steel

    Author : Anders Wilson; KTH; []
    Keywords : Duplex stainless steel; Microstructure; Phase transformations; Precipitates; Sigma phase; Kinetics; Thermodynamic calculation; Continuous cooling transformation diagram; Time temperature transformation diagram; Computer model.;

    Abstract : Duplex stainless steels consist of about equal fractions offerrite and austenite and are attractive due to their highcorrosion resistance against pitting corrosion and stresscorrosion cracking. The pitting corrosion resistance can bedescribed by the PREN value which is defined asPREN=%Cr+3.3*%Mo+16*%N. READ MORE

  6. 4. On the multiscale modeling of duplex stainless steel

    Author : Robert Lillbacka; RISE; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; duplex stainless steel; crystal plasticity; damage; Concurrent multiscale modeling; calibration;

    Abstract : This thesis deals with the modeling and simulation ofthe influence of the material substructure on the macroscopicmechanical properties of duplex stainless steel (DSS). Twosubscale levels and their interaction are considered: Grainstructure (mesoscale) and crystallographic structure (microscale). READ MORE

  7. 5. Sintering simulation framework for 316L stainless steel components manufactured by binder jetting

    Author : Alberto Cabo Rios; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sintering; sintering modelling; additive manufacturing; binder jetting; stainless steel.; dilatometry;

    Abstract : Binder Jetting (BJT) is an additive manufacturing (AM) technology allowing mass-production of small to medium-size metal components. BJT is a multi-step AM technology, where the geometrical shape of components is provided during the printing step, and the final properties are achieved through a second consolidation step - sintering.
