  2. 1. Hydrogen embrittlement and corrosion behavior of low-temperature carburized austenitic stainless steel

    Author : Xiao Qin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; low-temperature carburising; hydrogen embrittlement; Austenitic stainless steel; microstructure; corrosion behavior; expanded austenite;

    Abstract : For metallic components used in hydrogen environments, hydrogen embrittlement and corrosion have always been important considering potential failure risks. Among many metallic materials, austenitic stainless steel has found broad application because of its excellent corrosion and hydrogen embrittlement resistance. READ MORE

  4. 2. Welds in the lean duplex stainless steel LDX 2101 : effect of microstructure and weld oxides on corrosion properties

    Author : Elin M. Westin; John Ågren; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Duplex stainless steel; welding; weld metal; HAZ; nitrogen; manganese; austenite formation; phase balance; precipitates; pitting resistance; heat input; solidification; element loss; evaporation; deposition; weld oxides; discoloration; mechanical properties; thermo-mechanical simulation; Geeble; GTA; laser; LOM; SEM; EDS; TEM; Leco; EPMA; ferroxyl test; XPS; post weld cleaning; pickling; Materials science; Teknisk materialvetenskap;

    Abstract : Duplex stainless steels are a very attractive alternative to austenitic grades due to their higher strength and good corrosion performance. The austenitic grades can often be welded autogenously, while the duplex grades normally require addition of filler metal. READ MORE

  5. 3. Metal release from stainless steels and the pure metals in different media

    Author : Gunilla Herting; Inger Odnevall Wallinder; Lena Wegrelius; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; stainless steel; iron; chromium; nickel; metal release; artificial rain; synthetic body fluid; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : This study has been triggered by the fact that stainless steel is being increasingly used in new applications, where possible environmental effects may be a matter of concern. When stainless steel is exposed to a given environment, a key issue is the release of small amounts of the main alloying elements iron, chromium, nickel and molybdenum. READ MORE

  6. 4. Effects of composition and the production process on formability of austenitic stainless steels

    Author : Roger Andersson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Manufacturing Systems Engineering; Produktionsutveckling;

    Abstract : Formability of austenitic stainless steels is strongly influenced by the chemical composition, the internal texture and the deformation conditions. The purpose of this study is to determine how small variations in chemical composition and minor variations in the production process are influencing the formability of type 304 and 316 austenitic stainless steels.

  7. 5. Corrosion-included metal runoff from external constructions and its environmental interaction : a combined field and laboratory investigation of Zn, Cu, Cr and Ni for risk assessment

    Author : Sofia Bertling; Inger Odnevall Wallinder; Herbert E. Allen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental technology; Atmospheric corrosion; metal runoff; metal dispersion; soil; limestone; retention; Miljöteknik; Environmental engineering; Miljöteknik;

    Abstract : The 1990s has seen an increased awareness of possible environmental effects of corrosion-induced metal release from outdoor constructions. Considerable efforts have been initiated to perform critical assessments of possible risks of selected metals. Gaps of knowledge have been identified and research investigations started. READ MORE
