2. 1. Bioaccessibility of Stainless Steels : Importance of Bulk and Surface Features

   Author : Gunilla Herting; Inger Odnevall Wallinder; Stuart Lyon; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stainless steel; iron; chromium; nickel; corrosion; metal release; artificial rain; synthetic body fluids; acetic acid; surface oxide; surface finish; Surface and colloid chemistry; Yt- och kolloidkemi;

   Abstract : With increasing environmental awareness, the desire to protect human beings and the environment from adverse effects induced by dispersed metals has become an issue of great concern and interest. New policies, such as REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) within the European Community, have been implemented to reduce hazards posed by the use of chemicals on producers and downstream users.

4. 2. Stainless steel plasticity : material modelling and structural applications

   Author : Anders Olsson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel Structures; Stålbyggnad;

   Abstract : The thesis addresses stainless steel in construction with focus on plasticity and shear resistance of welded girders respectively. In the area of plasticity it comprises an account of an experimental study with emphasis on phenomenological observations followed by theorethical modelling. READ MORE

5. 3. Corrosion Fatigue of Stainless Steels

   Author : Jan Linder; KTH; []
   Keywords : Stainless steel; corrosion fatigue; crack propagation; spot weld;

   Abstract : The aim of this work was to investigate the effect ofchloride-containing environments on corrosion fatigueproperties for different stainless steels grades. The steelsinvestigated ranged from the standard 304 grade to thesuperaustenitic 654SMO and the superduplex SAF2507. READ MORE

6. 4. Passivation of Austenitic Stainless Steel

   Author : Lena Wegrelius; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stainless steel; chloride; molybdenum; passivation; hydrochloric acid; nitrogen; ESCA; dissolution;

   Abstract : The objective of this thesis is to study the corrosion resistance and passivation of high alloyed austenitic stainless steels exposed to hydrochloric acid. The introductory section gives a background to the subject; electrochemical measurements and surface analysis by the ESCA-technique (Electron Spectroscopy for Chemical Analysis). READ MORE

7. 5. 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
