  3. 2. High Temperature Corrosion of Cast Irons and Steels

    Författare :Frédéric Tholence; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; high temperature corrosion; cast steel; austenitic stainless steel; SiMo; cast iron; oxidation; exhaust gases; Ni-resist; LCF; ferritic stainless steel;

    Sammanfattning : During the last decades, tougher competition and stiffer government policies have forced the automotive industry into a race for safer, cleaner and more fuel-efficient vehicles at low cost. As a consequence, exhaust systems should resist to increased working temperatures. LÄS MER

  5. 4. The Effects of Morphology and Surface Oxidation of Stainless Steel Powder in Laser Based-Powder Bed Fusion

    Författare :Dmitri Riabov; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; additive manufacturing; powder surface; 316L stainless steel; oxides; oxidation; laser based-powder bed fusion; morphology; powder properties; powder production;

    Sammanfattning : Laser based-powder bed fusion (LB-PBF) is one of the many techniques within additive manufacturing (AM) that allows for near net shape manufacturing of metallic components. By using powder feedstock, it is possible to spread thin layers of powder and further selectively fuse powder in a repetitive manner until the component is completed. LÄS MER

  7. 5. Cold lap formation in Gas Metal Arc Welding of steel : An experimental study of micro-lack of fusion defects

    Författare :Peigang Li; Lars-Erik Svensson; Norbert Enzinger; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tandem GMAW; old laps; lack of fusion; Spatter; Overlap; Overflow; Manganese; Silicon; Oxides; Temperature; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : Cold laps are defined as micro-lack of fusion defects at the weld toe more or less parallel to the surface of the parent plate. These defects are known to negatively influence the fatigue properties of weldments. Previous studies suggest that cold lap formation can not be avoided completely in Gas Metal Arc Welding (GMAW).
